  1. Comment on “Piezonuclear decay of thorium” [Phys. Lett. A 373 (2009) 1956

    Kowalski, L.

    2010-01-01

    Cardone et al. [F. Cardone, R. Mignani, A. Petrucci, Phys. Lett. A 373 (2009) 1956] claim that cavitation speeds up radioactive decay of 228Th dissolved in water. The experimental evidence they presented was criticized by Ericsson et al. [G. Ericsson, S. Pomp, H. Sjöstrand, E. Traneus, Phys. Lett. A 373 (2009) 3795]. This Comment focuses on a presumably-ignored trivial effect that might be responsible for the reported experimental results. It also contains suggestions for improving the quality of future investigations.

    In the Letter [B.A. Nguyen, Phys. Lett. A 350 (2006) 174], a quantum exam protocol was presented. Here we show a cheating protocol, by which any student can get the other students' solution without being detected. Then we propose a possible modified protocol against this attacking strategy.

    We present simulations countering the claims in [R. Nair, H.P. Yuen, Phys. Lett. A 372 (2008) 7091] that the approximation given in [C. Ahn, K. Birnbaum, Phys. Lett. A 370 (2007) 131, quant-ph/0612058] for the eavesdropper's entropy on the encrypted key cannot be valid, and additionally discuss ways in which our views on security requirements differ from those given in [R. Nair, H.P. Yuen, Phys. Lett. A 372 (2008) 7091].

    Cardone, Fabio; Mignani, Roberto; Petrucci, Andrea

    2010-01-01

    In a Letter appearing in this issue of Physics Letters A, Kowalski raises some critical comments on the experiment [F. Cardone, R. Mignani, A. Petrucci, Phys. Lett. A 373 (2009) 1956] that we carried out by cavitating a solution of Thorium-228. The experiment highlighted the anomalous decay of Thorium, thus confirming the results previously obtained by Urutskoev et al. by explosion of titanium foils in solutions. In this Letter, we reply to these comments. We agree with Kowalski that critical comments are one of the key factors of the process to improve the quality of experiments and the interpretation of results. However we do hope that these comments together with the details provided in the replies will promote further and better experiments which are certainly worth performing in order to shed a brighter light on this issue, as Kowalski himself suggests in his comment.

    Cardone, Fabio; Mignani, Roberto; Petrucci, Andrea

    2009-10-01

    In a paper appearing in this issue of Physics Letters A, Ericsson et al. raise some critical comments on the experiment [F. Cardone, R. Mignani, A. Petrucci, Phys. Lett. A 373 (2009) 1956] we carried out by cavitating a solution of thorium-228, which evidenced its anomalous decay behaviour, thus confirming the results previously obtained by Urutskoev et al. by explosion of titanium foils in solutions. In this Letter, we reply to these comments. In our opinion, the main shortcomings of the criticism by the Swedish authors are due to their omitting of inserting our experiment in the wider research stream of piezonuclear reactions, and to the statistical analysis they used, which does not comply with the rules generally accepted for samples with small numbers. However, apart from any possible theoretical speculation, there is the basic fact that two different experiments (ours and that by Urutskoev et al.), carried out independently and by different means, highlight an analogous anomaly in the decay of thorium subjected to pressure waves. Such a convergence of results shows that it is worth to further carry on experimental investigations, in order to get either a confirmation or a disproof of the induced-pressure anomalous behaviour of radioactive nuclides even different from thorium.

    da Silva, Clarissa O.; da Silva, Edilson C.; Nascimento, Marco A. C.

    2003-11-01

    In a recent Letter, Pliego [Chem. Phys. Lett. 367 (2003) 145] has raised some questions about the methodology that we have employed for calculating p Ka values in aqueous solutions. In this comment we show that the problem with Pliego's analysis is the fact that he used Ben-Naim's definition of Δ Gsol for both the solute and the solvent, which implies that the concentration, for both components, should be equal to 1 M. For the solute, this is a reference state fully compatible with the quantum description, but for the solvent this choice is unphysical, as discussed in the Letter.

    Subjecting a solution of 228Th to ultrasound (20 kHz, 100 W), Cardone et al. [F. Cardone, R. Mignani, A. Petrucci, Phys. Lett. A 373 (2009) 1956] claim to observe an increase in the transformation or decay rate of 228Th by a factor of 10 4. The evidence provided seems however far from conclusive and in part contradictory to the claims made. In fact, looking at the presented data we find it cannot be taken as justification to discard the null hypothesis, namely, that the data from exposed and non-exposed samples are drawn from the same distribution. We suggest a number of additional tests that should be made in order to improve the quality of the study and test the hypothesis of so-called piezonuclear reactions.

    Feng, F.; Ma, J. P.; Wang, Q.

    2009-06-01

    A new method is proposed to calculate wave functions in kT-factorization in [H.-n. Li, S. Mishima, Phys. Lett. B 674 (2009) 182, arXiv:0808.1526] as a comment about our paper [F. Feng, J.P. Ma, Q. Wang, Phys. Lett. B 674 (2009) 176, arXiv:0807.0296]. We point out that the results obtained with the method are in conflict with the translation invariance and depend on the chosen contours for loop-integrals. Therefore, the method is in principle unacceptable and the results with the method cannot be correct.

    2008-11-01

    We show that the insecurity claim of the αη cryptosystem made by C. Ahn and K. Birnbaum in [C. Ahn, K. Birnbaum, Phys. Lett. A 370 (2007) 131] under heterodyne attack is based on invalid extrapolations of Shannon's random cipher analysis and on an invalid statistical independence assumption. We show, both for standard ciphers and αη, that expressions of the kind given by Ahn and Birnbaum can at best be interpreted as security lower bounds.

  10. Comment on “Deterministic six states protocol for quantum communication” [Phys. Lett. A 358 (2006) 85

    El-Orany, Faisal A. A.

    2010-02-01

    In [J.S. Shaari, M. Lucamarini, M.R.B. Wahiddin, Phys. Lett. A 358 (2006) 85] the deterministic six states protocol (6DP) for quantum communication has been developed. This protocol is based on three mutually unbiased bases and four encoding operators. Information is transmitted between the users via two qubits from different bases. Three attacks have been studied; namely intercept-resend attack (IRA), double-CNOT attack (2CNOTA) and quantum man-in-the-middle attack. In this Letter, we show that the IRA and 2CNOTA are not properly addressed. For instance, we show that the probability of detecting Eve in the control mode of the IRA is 70% instead of 50% in the previous study. Moreover, in the 2CNOTA, Eve can only obtain 50% of the data not all of it as argued earlier.

  11. Comment on ``Three-dimensional photonic-crystal emitter for thermal photovoltaic power generation'' [Appl. Phys. Lett. 83, 380 (2003)

    NASA Astrophysics Data System (ADS)

    Trupke, Thorsten; Würfel, Peter; Green, Martin A.

    2004-03-01

    In a recent article, Lin et al. [Appl. Phys. Lett. 83, 380 (2003)] reported on the light-emitting properties of three-dimensional tungsten photonic crystals and their potential applications as improved thermal emitters in thermophotovoltaic (TPV) systems. Their findings have attracted considerable interest throughout the media and the application of this type of materials has been praised as a potential superior future energy source; e.g., in waste heat-driven electrical generators (http://www.photonics.com). The results of the theoretical modeling in the work of Lin et al. suggest that a TPV system can achieve higher heat to electric energy conversion efficiencies in combination with a three-dimensional tungsten photonic crystal than with any conventional selective thermal emitter. These theoretical results are based on the experimental observation that the photonic crystal, when heated to a given temperature, emits more radiation in certain spectral regimes than a black body of the same temperature. This experimental observation shall briefly be discussed here.

    2007-02-01

    In a recent article [M. Consoli, E. Costanzo, Phys. Lett. A 333 (2004) 355], M. Consoli and E. Costanzo have investigated classical and modern aether drift experiments and explored the narrow window for detection of a preferred reference frame. This Letter proposes an easy to perform variant of Fizeau's experiment, which may confirm or deny Consoli Costanzo's claims.

    Numerical results for the function (1 -EK /E0) kcot ⁡δ0R, as given in Phys. Lett. B 764 (2017) 196, are revised. Fig. 2 and Tables 2 and 3 should be replaced by the following corresponding figure and tables. The conclusions of the original paper remain unchanged.

  14. Comment on “Scaling behavior of one-dimensional Pt chains migration on Pt(110)-(1×2) surface”. [Phys. Lett. A 268 (2000) 413

    NASA Astrophysics Data System (ADS)

    Montalenti, F.; Ferrando, R.

    2000-11-01

    We show that the recently proposed scaling laws [see G. Zhuang, W. Wang, Phys. Lett. A 268 (2000) 413] for chain diffusion on missing-row Pt(110) have no real meaning, since they cannot be extended outside the narrow chain-length range which has been considered by Zhuang and Wang. The only asymptotic scaling law gives a chain mobility which is inversely proportional to the chain length; however this asymptotic scaling behaviour is not physically important due to the occurrence of multiple upward promotions for long chains.

    Clarifications about the source of error in [Phys. Lett. A 371 (2008) 2271] of momentum-space information measures are given along with the revised estimates which satisfy all the points commented upon by Astashkevich. We note that the position-space quantities calculated previously remain unchanged. Our main conclusion, that the inter-nuclear distance, R, dependence of statistical complexity and Fisher-Shannon measure derived from the simple Coulson wave function contain significant information on molecular bonding in H2+, remains qualitatively valid in the light of calculations using more accurate wave functions as reported by Astashkevich.

    van Mourik, Tanja

    2009-04-01

    A Letter by Gu et al. [J. Gu, J. Wang, J. Leszczynski, Y. Xie, H.F. Schaefer III, Chem. Phys. Lett. 459 (2008) 164] presented MP2/6-31+G(d) and MP2/TZVPP stacking energies for the uracil and thymine dimers, with the aim to assess the performance of the new M06-2X density functional. However, the stacking energies were not corrected for the basis set superposition error (BSSE). Here we show that correction for this error dramatically changes the results. BSSE correction severely reduces the stacking energy of the thymine dimer, whereas the stacked uracil dimer structure considered by Gu et al. is not even a minimum on the MP2/6-31+G(d) potential energy surface.

    The scale of the ordinate axis of Fig. 4 on page 226 of PLB 746 (2015) 223 was incorrect. The new version of Fig. 4 (which is "Fig. 1" in the present note) with the correct ordinate axis is given here (upper part). The lower part shows the previous version. Five potential wells and barriers are shown. Considering a sequential process two barriers are relevant for the decay, with equal barriers for the symmetric cases with a smaller fragment at the center (in these cases only one barrier is shown). For the asymmetric case of 70Ni + 50Ca + 132Sn, two different barriers appear, denoted as (B1) and (B2), which correspond to the interactions of the middle cluster 50Ca with the outer nuclei 70Ni and 132Sn, respectively. In a sequential mechanism the separation of 132Sn from the other part via the barrier B2 having the smaller height, is favoured for the first step. For the second step the barrier (B1) between Ni and Ca, appears at smaller distances (dot-dashed curve) and is higher. The order of the barriers of the five channels is unchanged, compared to the figure in Ref. W. von Oertzen et al., Phys. Lett. B 746 (2015) 223.

    Quinn, C. D.; Glen, R. A.; Diessel, C. F. K.

    2008-05-01

    On the basis of a numerical simulation, Klose [Earth Planet. Sci. Lett. 256: 547-553 (2007)] proposed that the MW = 5.2-5.6 earthquake that nucleated beneath Newcastle (New South Wales, Australia) at 10.30 AM December 28, 1989 (AEST), was the result of 200yr of coal mining in the region. We argue here that Klose's [Earth Planet. Sci. Lett. 256: 547-553 (2007)] ultimate conclusion is not supported by his own model or by available geological and seismic data. In particular, the 1989 Newcastle earthquake was not anomalous with respect to regional seismic activity.

    In a recent Letter [R. Friedberg, J.T. Manassah, Phys. Lett. A 372 (2008) 2514] Friedberg and Manassah argue that effect of virtual photons has serious consequences for large atomic samples. Here we show that such effect is negligible for evolution of a uniformly excited atomic state prepared by absorption of a single photon.

    In their Comment on our recent Letter [R.A. Klein, M.A. Zottola, Chem. Phys. Lett. 419 (2006) 254-258], Feller and Peterson point out that density functional theory combined with the Pople triple split-valence basis-set 6-311++G(2d,p), does indeed perform well in comparison to second-order perturbation and coupled cluster theory in combination with correlation-consistent basis-sets for the prediction of bond lengths and harmonic frequencies but does not provide acceptable accuracy for dissociation energies. MPW1PW91/6-311++G(2d,p) is, therefore, highly suitable and computationally efficient for generating starting structures for subsequent single-point (SP) calculations at higher and more computationally expensive levels of theory.

    2004-03-01

    We have recently discovered a significant mistake in this paper. In the original data set used for our interpretation, U-Pb detrital zircon ages for two samples were inadvertently switched. The error was caught after new data were obtained on similar rocks. The error evidently occurred during uploading of data from laboratory computers into spreadsheets. The mix-up has been verified by re-analyzing a subset of zircons from each of the original samples. As a consequence, in the original paper, the formation names for two samples - La Cebila and Cerro Totora - are switched.

    The recently proposed term radicalicity was described as a measure of the reactivity of a free radical Q*, i.e., a kinetic quantity. Here it is shown that in fact it is simply a frame-shifted version of the well-known bond dissociation energy, a thermodynamic quantity. Hence its use is discouraged.

    We reexamine the effect of kinetic decoupling on the relic density of the non-relativistic particles whose annihilation rate is increased by Sommerfeld enhancement. I claim that the result in Dent et al. (2010) [1] is wrong in the case of kinetic decoupling for small coupling constant α.

    In [1] it was considered a rotating magnetic field Bi =ɛijk∂jAk that violates the Bianchi identities for the standard photon (i.e. the vector gauge field A). It is claimed by the author that this construction justifies the existence of a physical pseudo-photon (a pseudo-vector gauge field C) independently of the detectability of magnetic monopoles [2]. This is an overstatement, in particular the author failed to notice that the construction presented in [1] is, in standard electromagnetism, unphysical. Considering the usual Maxwell equations in vacuum a magnetic field does not exist by itself, it needs to be generated by some source. Usually an electric current or its equivalent (e.g a permanent magnet) [3]. By properly considering the electric currents that generate the magnetic field Bi in the Maxwell action the standard vector field A is enough to describe most physical systems and generally has regular solutions.

    In Eq. (A.13) θ (1 -η1 -η2) should be replaced by θ (ξ1 -ξ2) and the result for the integral I4 should be multiplied by 2/3. Eq. (A.14) corresponds to the contribution of the pole of the D (l1) propagator to Eq. (A.11). The contribution of the D (l1 +l2) pole can be easily obtained from this result by redefining the external momenta. The last term in Eq. (23) should be replaced by - 3/4 - 184 x + 264x2 - 184x3 + 34x4 3 (1 - x)x2 . The numerators of the rational functions in the first and the second lines of Eq.

    X-ray absorption by matter has long been described by the famous Beer-Lambert law. Here we show how this fundamental law needs to be modified for high-intensity coherent x-ray pulses, now available at x-ray free electron lasers, due to the onset of stimulated elastic forward scattering. We present an analytical expression for the modified polarization-dependent Beer-Lambert law for the case of resonant core-to-valence electronic transitions and incident transform limited x-ray pulses. Upon transmission through a solid, the absorption and dichroic contrasts are found to vanish with increasing x-ray intensity, with the stimulation threshold lowered by orders of magnitude through a super-radiative coherent effect. Our results have broad implications for the study of matter with x-ray lasers.

    The inflaton back-reaction was underestimated in Section 5.2 of [1]: In equation (34), the string-frame length-scale Rs2 = M ˜ gs(ls / 2 π)2 of the KS-solution was used instead of the Einstein frame length-scale RE2 = M ˜ gs1/2(ls / 2 π)2. Therefore, the r.h. side of equation (34) should contain a factor gs- 1/2 instead of gs-2. The analogous correction of equation (35) results in a factor of gsSUP>-1/2 also in the inflaton energy density. Consequently, there should be no factor of gs in equation (36) which means that the inflaton back-reaction starts to deform the geometry strongly once the field excursion approaches the Planck-scale.

    Within the framework of the complex-scaling method, the expectation value of a given complex-scaled operator Q ˆ is given by ≪ Q ˆ ≫ =Re ≪ψL | Q ˆ |ψR ≫[1]. I have noticed that there is a misunderstanding in the article [2]. Namely, I have incorrectly written in Section 4 that for every operator Q ˆ the imaginary part of ≪ψL | Q ˆ |ψR ≫ can be interpreted as the indeterminacy ΔQ, (ΔQ) 2 =Re ≪ψL |(Q ˆ - ≪ Q ˆ ≫) 2 |ψR ≫. According to [1], one can show that the imaginary part of ≪ψL | Q ˆ |ψR ≫ is the uncertainty in the determination of the mean value only in the case when the operator Q ˆ commutes with the Hamiltonian H ˆ , (ΔQ) 2 = -(Im ≪ψL | Q ˆ |ψR ≫) 2. In light of the above, the discussion in Section 4 regarding the physical meaning of the imaginary parts of S and Slin is incorrect. More constructive analysis is still needed to understand the physical meaning of Im ≪ψL | Q ˆ |ψR ≫ for the operators Q ˆ that do not commute with H ˆ . I apologize to the readers of Physics Letters A for the error.

    Brett et al. (2015) proposed a kimberlite factory model that ;…involves carbonatitic proto-kimberlite melts preferentially assimilating Opx xenocrysts as they transit the cratonic mantle lithosphere to evolve into silicic-hydrous melts that reach olivine saturation during ascent; (p. 130). A cornerstone of this model is a specific, carbonatitic composition of proto-kimberlite melts ascending through the subcratonic lithospheric mantle ;…whereby parental carbonatitic magmas are progressively converted to kimberlite (e.g., Russell et al., 2012, 2013; Bussweiler et al., 2015); (p. 120). The model by Brett et al. (2015) is based on observations of ;the carbonate-sealed cracks; in olivine that ;…strongly support to the hypothesis that all kimberlite magmas originate as carbonatitic-melts (e.g., Russell et al., 2012, 2013; Kamenetsky et al., 2013; Pilbeam et al., 2013; Kamenetsky and Yaxley, 2015; Bussweiler et al., 2015).; (p. 129). While the major thrust of the study by Brett et al. (2015) hinges on the premise that the parental kimberlite melt is carbonatitic, the overwhelming majority in the kimberlite community still prefers a carbonated ultramafic/ultrabasic composition for parental kimberlite melts. Thus the suggestion that kimberlites have an initial carbonatite composition is not less than ;a paradigm shift; in the kimberlite petrology. It appears that a carbonatite origin for kimberlites has been proposed in many studies that significantly pre-date the publications starting from 2012 that they cite, but which unfortunately are overlooked by Brett et al. (2015). It is, therefore, worth acknowledging the research which has previously advanced this unorthodox idea.

    The Kamenetsky (2016) comment on the Kimberlite Factory model proposed by Brett et al. (2015) asserts, ;A cornerstone of this model is a specific, carbonatitic composition of proto-kimberlite melts ascending through the sub-cratonic lithospheric mantle; and ;… the major thrust of the study hinges on the premise that the parental kimberlite melt is carbonatitic;. This is a clear misstatement of our central thesis, which is to utilize the attributes of olivine xenocrysts to constrain the physical ascent of kimberlite. Brett et al.'s study does not hinge on the premise that parental kimberlite melt is carbonatitic. Rather, our interpretation that kimberlite melt originates as near carbonatitic hinges on our novel observation that early ;carbonate sealed cracks provide evidence of melt being drawn into decompression cracks and precipitating; (p. 129). Our connection between this observation and our interpretation is tied explicitly to earlier published works ;in this regard, the carbonate-filled sealed cracks strongly support to the hypothesis that all kimberlite magmas originate as carbonatitic-melts (e.g.,Russell et al., 2012, 2013;Kamenetsky et al., 2013; Pilbeam et al., 2013; Kamenetsky and Yaxley, 2015; Bussweiler et al., 2015); (p. 129). To state that our interpretation is based on a pre-existing bias towards a model of a carbonatitic origin of kimberlite magmas is incorrect. Rather, our new observational data independently demonstrates that the presence of carbonate-sealed cracks formed during kimberlite ascent.

    The authors reported in their letter some outstanding experimental results of spin excitations in nano-particles investigated by near-field Brillouin scattering. They conclude from their observations that existing theories -- in particular micromagnetic simulations -- do not correctly describe the behavior of the spin modes. Since excellent agreement has been reported between spin-wave mode frequencies obtained from Brillouin scattering experiments and those obtained from micromagnetic-based simulations, it is somewhat surprising that the simulations should fail for the particles investigated in Ref. 1. In the literature, there is also evidence of various kinds and degrees of mode localization when exchange competes with dipolar interactions. When dipolar long-range interactions are taken into account, the eigenmodes can be seen as the superposition of plane waves, leading to different localizations and in particular to the appearence of bulk-dead modes. We have simulated the normal modes of the particles used in Ref. 1, with the dynamical matrix method; the results are shown in Fig. 1 for different values of the applied field. In addition to the lowest frequency non-localized mode (1-BA), several localized modes are present. Large particles exhibit modes with oscillations along the field direction;8 for such modes, we use the label n-BA-loc, with n the number of nodes. While the profile of the pure end-mode, i.e., 0-BA-loc, has its maximum at the edge with the amplitude monotonously decreasing toward the interior of the ellipse, as correctly described by the authors, the localized modes with n > 0, not considered by them, do not have this characteristic: see inset of Fig. 1. Based on Fig. 1, we believe that the assumption that the mode they observe is 'the' localized spin mode is not correct. Instead, we believe that the mode detected in the experiment at H > 700 Oe is a combinations (due to non-linear excitation conditions of the experiment) of several n-BA-loc modes, with n?>?0. In this picture, the sharp peaks of the n-BA-loc modes are smoothed in the experimental measurements, thanks to the superposition of modes with different nodal lines. Finally, at 350 Oe, the measured profile and frequency suggest that the mode seen in the experiment may be well due to the 1-BA mode. The observed change in mode profile at 350 Oe is substantiated by the frequency behavior shown in Fig. 3(b) of Ref. 1, where it can be observed that the frequency of the low-field point does not lie on the same curve as the high-field points. In summary, before concluding that micromagnetic-based simulations of spin wave modes in nano-particles are unreliable, we believe that it is necessary to await either the simulation of large particles using small cell sizes or for more exhaustive experiments reaching lower frequencies on particles of varying size. The comparison of calculations with experiment would greatly benefit if the authors were to provide the field dependence of all the modes detected in their experiment (in order to achieve a proper assignment).

    Due to an error in our numerical code, the results about the evolutions of the scalar field Φ, the Hubble rate H and scale factor a in the deformed model presented in the paper are incorrect. The corrected results are depicted in Figs. 1-3 respectively. As results, one can find that when neglecting reheating the universe would experience multi cycles of expansions and contractions as showed by the damped oscillating behavior of H in Fig. 2. Each cycle contains non-singular bounces between expanding and contracting phases, as showed in Fig. 3. Gradually the universe approaches to a static universe. This is similar to inflation. Without reheating the inflaton field will oscillates with damped amplitude around the minimum of its potential and the universe enters into the static phase in the future if the cosmological constant vanishes. However, in a real universe reheating is necessary and it will interrupt the oscillations and lead the universe to the radiation dominated epoch. In the model considered in this paper, the exit from oscillation to the hot expansion depends on the details of reheating, but we can still get the general idea about how this exit appears. The Friedmann equation can be rewritten as

    We revisit the derivation of the equation modeling envelope waves in a discrete nonlinear electrical transmission line (NLTL) considered a few years back in Physics Letters A 373 (2009) 3801-3809. Using a combination of rotating wave approximation and the Gardner-Morikawa transformation, we show that the modulated waves are described by a new type of extended nonlinear Schrödinger equation. In addition the expressions of several coefficients of this equation are found to be strongly different from those given earlier. As a consequence, key relationships between these coefficients that sustained the previous analysis are broken.

    The authors regret that the 10Be concentrations and uncertainties displayed in Table 2 were reported erroneously in the original version. The corrected table appears below for the reader's convenience. We emphasize that the calculations of erosion rates and integration times were performed using the correct data. Thus, these corrections don't affect the discussion and conclusions presented in this study.

    Pt/Co/heavy metal (HM) tri-layered structures with interfacial perpendicular magnetic anisotropy (PMA) are currently under intensive research for several emerging spintronic effects, such as spinorbit torque, domain wall motion, and room temperature skyrmions. HM materials are used as capping layers to generate the structural asymmetry and enhance the interfacial effects. For instance, the Pt/Co/Ta structure attracts a lot of attention as it may exhibit large Dzyaloshinskii-Moriya interaction. However, the dependence of magnetic properties on different capping materials has not been systematically investigated. In this paper, we experimentally show the interfacial PMA and damping constant for Pt/Co/HM tri-layered structures through time-resolved magneto-optical Kerr effect measurements as well as magnetometry measurements, where the capping HM materials are W, Ta, and Pd. We found that the Co/HM interface plays an important role on the magnetic properties. In particular, the magnetic multilayers with a W capping layer features the lowest effective damping value, which may be attributed to the different spin-orbit coupling and interfacial hybridization between Co and HM materials. Our findings allow a deep understanding of the Pt/Co/HM tri-layered structures. Such structures could lead to a better era of data storage and processing devices.

    The authors have discovered a calculation error in the concentration data for U, Th and Pb. This error does not affect any measured isotopic compositions: 206Pb/204Pb, 207Pb/204Pb, 238U/204Pb, 232Th/204Pb, and 235U/204Pb; these all remain the same. None of the Fe isotope data are affected. Hence, none of the conclusions for open or closed-system U-Th-Pb behavior are affected, nor the conclusions of a redox gradient between shallow- and deep-water U contents. The magnitude of the shallow- and deep-water U content contrast remains the same, where U contents in shallow seawater are estimated to have been about three times that of deep-water samples.

    We point out and correct the erroneous numerical results calculated by H.E. Montgomery Jr. and K.D. Sen concerning the statistical complexity and the Fisher-Shannon information measure for the ground state H+2 molecule ion as a function of internuclear distance in momentum space and as a product in position and momentum spaces. In addition we have shown that Coulson-type wave function approximation used by authors leads to notable (up to almost 20%) discrepancies between such approximated results and exact ones.

    This is in response to Catalán's objection to our use of isopolarizability conditions in the resolution of the absorption and fluorescence spectra of the s-cis and s-trans all-trans-1.6-diphenyl-1,3,5-hexatriene (ttt-DPH) conformers and the resolution of the fluorescence spectrum of the s-trans conformer to 21Ag → 11Ag and 11Bu → 11Ag spectra. Contrary to Catalán's assertion, we did not assume identical solvatochromic and thermochromic responses of ttt-DPH to medium changes. Those responses depend on a complex combination of factors that can differ from molecule to molecule.

    Ultraprecise fabrication of three-dimensional (3D) microstructures comes up to be one of the most important issues in two-photon induced photopolymerization. To date, it has been difficult to fabricate 3D microstructures without any deformation due to the surface tension between a rinsing material and solidified microstructures during the developing process: In general, the surface tension significantly affects the precision of the resulting 3D microstructures. To overcome this problem, the authors propose a simple and effective laser scanning method to reinforce the strength of 3D microstructures without loss of precision. Overall, a complex 3D artistic sculpture such as "The Thinker" was reproduced in the controlled ultraprecise form, which shows that the proposed method enables the fabrication of 3D patterns with dramatically improved precision and stability.

    A search for time-integrated CP violation in D0 -> h-h+ (h=K, pi) decays is presented using 0.62 fb^-1 of data collected by LHCb in 2011. The flavor of the charm meson is determined by the charge of the slow pion in the D*+ -> D0 pi+ and D*- -> D0bar pi- decay chains. The difference in CP asymmetry between D0 -> K-K+ and D0 -> pi-pi+, Delta ACP = ACP(K-K+) - ACP(pi-pi+), is measured to be [-0.82 \\pm 0.21(stat.) \\pm 0.11(syst.)]%. This differs from the hypothesis of CP conservation by 3.5 standard deviations.

    In the cross section for single-inclusive jet production in electron nucleon collisions, the distribution of a quark in an electron appears at next-to-next-to-leading order. The numerical calculations in Ref. [1] were carried out using a perturbative approximation for the distribution of a quark in an electron. We point out that that distribution receives nonperturbative QCD contributions that invalidate the perturbative approximation. Here, those nonperturbative effects enter into cross sections for hard-scattering processes through resolved-electron contributions and can be taken into account by determining the distribution of a quark in an electron phenomenologically.

    In a recent contribution [1], Johnson et al. reported the equilibrium isotope fractionation factor between dissolved Fe(II) and Fe(III) in aqueous solutions at pH=2.5 and 5.5. They suggest that because the iron isotope fractionation observed in their experiments spans virtually the entire range observed in sedimentary rocks, Fe(II)–Fe(III) aqueous speciation may play a major role in determining iron isotope variations in nature where Fe(II) and Fe(III) can become physically separated. They discounted earlier conclusions by us and others [2] ;  [3] that significant equilibrium fractionation between specific coexisting Fe(II)- or Fe(III)-aqueous complexes (e.g., between aqueous Fe(II)(OH)x(aq)and Fe(II)(aq) ion) is capable of producing iron isotope contrasts that can be preserved in nature. This is an important contribution not only because the authors recognize the importance of abiotic equilibrium iron isotope fractionation in nature in contrast to previous assertions [4], but also because it will help to focus discussion on the development and evaluation of experimental approaches that can reveal abiotic fractionation mechanisms. However, in this Comment we propose that the experiments presented in this paper cannot be interpreted as straightforwardly as Johnson et al. contend. In particular, we show that in one of their critical experiments attainment of either isotope mass balance or equilibrium was not demonstrated, and thus the results of that experiment cannot be used to calculate an Fe(II)–Fe(III) equilibrium fractionation factor.

  6. Comment on ``Pseudo-Jahn Teller and TICT-models: a photophysical comparison of meta-and para-DMABN derivatives'' [Chem. Phys. Lett. 305 (1999) 8] The PICT model for dual fluorescence of aminobenzonitriles

    Due to the larger admixture of charge transfer (CT) in the intramolecular charge transfer (ICT) state than in the locally excited (LE) state of dual fluorescent molecules such as 4-(dimethylamino)benzonitrile, the radiative rate constant kf'(ICT) is smaller than kf(LE), irrespective of the ICT molecular structure. The validity of the TICT or PICT model can therefore not be tested with these data. The absence of dual fluorescence for 4-(methylamino)benzonitrile, 3-(dimethylamino)benzonitrile and two dicyano- N, N-dimethylanilines, which cannot be explained by the TICT hypothesis, is caused by their large energy gap Δ E(S 1, S 2), which prevents the ICT state from becoming lower in energy than LE.

  7. Corrigendum to “Suppression of Υ production in d+Au and Au+Au collisions at √ SNN = 200 GeV" [Phys. Lett. B 735 (2014) 127-137

    We report measurements of Υ meson production in p + p, d + Au, and Au+Au collisions using the STAR detector at RHIC. We compare the Υ yield to the measured cross section in p + p collisions in order to quantify any modifications of the yield in cold nuclear matter using d + Au data and in hot nuclear matter using Au+Au data separated into three centrality classes. Our p + p measurement is based on three times the statistics of our previous result. We obtain a nuclear modification factor for Upsilon (1S + 2S + 3S) in the rapidity range |y| < 1 in d + Au collisions of RdAu = 0.79 ± 0.24(stat.) ± 0.03(syst.) ± 0.10(p + p syst.). A comparison with models including shadowing and initial state parton energy loss indicates the presence of additional cold-nuclear matter suppression. Similarly, in the top 10% most-central Au + Au collisions, we measure a nuclear modification factor of R AA = 0.49 ±0.1(stat.) ±0.02(syst.) ±0.06(p + p syst.), which is a larger suppression factor than that seen in cold nuclear matter. Our results are consistent with complete suppression of excited-state Upsilon mesons in Au + Au collisions. The additional suppression in Au + Au is consistent with the level expected in model calculations that include the presence of a hot, deconfined Quark–Gluon Plasma. However, understanding the suppression seen in d + Au is still needed before any definitive statements about the nature of the suppression in Au + Au can be made.

  9. Comment on the article ;Cation-π interaction of Ag+ with [6]helicene: An experimental and theoretical study; by E. Makrlík et al. [Chem. Phys. Lett. 633 (2015) 105-108

    In an article dedicated to the structure and energetics of the adduct Ag+/[6]helicene (Chem. Phys. Letters 633 (2015) 105-108), the authors measured an energy threshold for the dissociation into Ag0 and ([ 6 ]helicene) +rad , using collision induced dissociation in an ion trap mass spectrometer. The result is incorrectly interpreted in term of a bond dissociation energy (BDE) related to the formation of Ag+ and neutral [6]helicene. In this Comment, the initial experimental result is converted into the true BDE using ionization energies of Ag0 and [6]helicene. The experimental method, accuracy and significance of this BDE in term of cation/π interaction, are discussed.

    The objective of this Letter is both to report the permeability results of a linezolid-based sulfenamide prodrug in an MDCK cell model (enterocyte surrogate system) and to discuss the strategic implications of these results for considering sulfenamide prodrugs to enhance the oral delivery of weakly acidic NH-acids (e.g., amides, ureas, etc.). The two main findings from this study are that the sulfenamide prodrug does not appear to survive intracellular transport due to conversion to linezolid and that there appears to be an apically-oriented surface conversion pathway that can additionally serve to convert the sulfenamide prodrug to linezolid upon approach of the apical membrane. It is hoped that these findings, along with the discussion of the strategic implications, will facilitate a greater awareness of the potential strengths and weaknesses inherent in the sulfenamide prodrug approach for enhancing the oral delivery of weakly acidic NH-acid drugs.

    Here we report the X-ray structures of chemically synthesized HIV-1 protease and the inactive [D25N]HIV-1 protease complexed with the ketomethylene isostere inhibitor Ac-Thr-Ile-Nlepsi[CO-CH(2)]Nle-Gln-Arg.amide at 1.4 and 1.8A resolution, respectively. In complex with the active enzyme, the keto-group was found to be converted into the hydrated gem-diol, while the structure of the complex with the inactive D25N enzyme revealed an intact keto-group. These data support the general acid-general base mechanism for HIV-1 protease catalysis.

    In previous studies, we have identified a family of benzo[b]furan and benzo[b]thiophene derivatives linked to amino sugars (1-6) that are cytotoxic to a range of cancer cell lines. We describe here an exploration of the effect of structural modification of the amino group on one of the carbohydrate residues (4-amino-2,3,4,6-tetradeoxy-α-l-threo-hexopyranoside) on in vitro cytotoxicity. It has been found that maintaining at least one basic functional group around the C-4 position in the carbohydrate moiety is crucial for cytotoxicity. Furthermore, it appears that modifications around the C-4 position are limited by suitable hydrophilic/hydrophobic and/or ionic interactions, as well as steric constraints.

    In our previous paper [1] we obtained a full classification of nonequivalent quasitriangular quantum deformations for the complex D = 4 Euclidean Lie symmetry o (4 ; C). The result was presented in the form of a list consisting of three three-parameter, one two-parameter and one one-parameter nonisomorphic classical r-matrices which provide 'directions' of the nonequivalent quantizations of o (4 ; C). Applying reality conditions to the complex o (4 ; C)r-matrices we obtained the nonisomorphic classical r-matrices for all possible real forms of o (4 ; C): Euclidean o (4), Lorentz o (3 , 1), Kleinian o (2 , 2) and quaternionic o⋆ (4) Lie algebras. In the case of o (4) and o (3 , 1) real symmetries these r-matrices give the full classifications of the inequivalent quasitriangular quantum deformations, however for o (2 , 2) and o⋆ (4) the classifications are not full. In this paper we complete these classifications by adding three new three-parameter o (2 , 2)-real r-matrices and one new three-parameter o⋆ (4)-real r-matrix. All nonisomorphic classical r-matrices for all real forms of o (4 ; C) are presented in the explicit form what is convenient for providing the quantizations. We will mention also some applications of our results to the deformations of space-time symmetries and string σ-models.

    We have identified a bias in the calculation of the cross section of J / ψ production measured in the e+e- channel at central rapidity (| y | < 0.9) [1]. The acceptance and efficiency corrections were evaluated using a Monte Carlo simulation, based on PYTHIA [2,3], which did not include the radiative decays of J / ψ (J / ψ →e+e- γ). In these decays the reconstructed dielectron invariant mass, me+e-, is biased towards smaller values than the nominal J / ψ mass, since the photon contribution is neglected. As a consequence, the fraction of signal events in the me+e- range 2.92-3.16 GeV/c2 was overestimated by about 10%. Moreover, the requirement of the transverse momentum of the daughter electrons being larger than 1 GeV/c is more selective for radiative than non-radiative J / ψ decays. Therefore, the J / ψ acceptance was also overestimated by about 5%.

    The authors regret an error related to the calculation of the 'calcite-aragonite mixing' trend presented in the paper, which caused an incorrect illustration of the above trend in a plot with δ 44 / 40Ca versus Sr-concentration coordinates (i.e., Fig. 5). The correct 'calcite-aragonite mixing' trend is shown below, and the amended mass balance equations used for the calculation of this trend are also listed below in the corrected Appendix A (i.e., an equivalent to the last page of the original Appendix).

    Our paper (Vannucchi et al., 2015) focuses on geologic evidence for shock metamorphism found at the epicentral region of the 1908 Tunguska event. None of the currently proposed bolide explanations for the 1908 event can produce the shock pressures indicated by the geological evidence described in Vannucchi et al. (2015). If the 1908 event would have generated these pressures over the epicentral region, an observable crater should have also formed. The comment by Melott and Overholt discusses the possibility that a 1908 cometary bolide strike in Tunguska cannot be excluded because of the absence of a detectable 14C increase at this site. They dispute the findings of a recent Liu et al.'s (2014) study that an East Asian comet impact recorded by eyewitness accounts in 773 AD was coincident with a detectable 14C increase in regional South China Sea corals that grew at that time. Their point, whether true or not, is fairly peripheral to our study because the bolide hypothesis for the 1908 Tunguska event, no matter the nature of the bolide itself, does not provide a viable explanation for the geological evidence of shock metamorphism found at the 1908 Tunguska site. Furthermore, as we discuss in our paper, the probability of a prior large impact-shock event having occurred at the site of the 1908 event is extremely low, suggesting that a terrestrial shock-generating mechanism may be linked to the resolution of the Tunguska enigma. Our preferred resolution is that a terrestrial hyper-explosive gas release event, a Verneshot (Morgan et al., 2004), created the large shock-event during the emplacement of the Siberian Traps. In this scenario, the 1908 Tunguska event was due to a much smaller gas-burst that re-used the lithospheric weakness created by the ancient Verneshot. Melott and Overholt's discussion regarding the existence and size of regional and global 14C anomalies related to cometary impacts seems, therefore, to be better addressed in response to the work of Liu et al. (2014), as appears to be done in a paper and preprint that Melott and Overholt self-cite in their comment.

    This corrigendum refers to an error in the CMS excluded regions in the scattering of dark matter (DM) particles on nucleons as a function of the DM mass (mDM) in Ref. [1]. A translation formula, used to relate the DM-nucleon interaction cross section to the mass of the dark matter mediator, neglected a dependence on mDM by using the nucleon mass in place of the reduced mass of the DM-nucleon system. The excluded range in the DM-nucleon interaction cross section in Fig. 5 of Ref. [1] was incorrectly shown as being independent of mDM at low values of mass, roughly below 40 GeV. The correct CMS excluded region for mDM > 1 GeV, where the translation formula is reliable, is presented here in Fig. 1, which replaces Fig. 5 of Ref. [1].

    The comment by Schmieder et al. (in press) concentrates on the viability of the quartz planar microdeformation features (PMFs) (or deformation lamellae) presented by Vannucchi et al. (2015) to infer the presence of shock metamorphism in the area of the 1908 Tunguska event. Their comment focuses on two points: The quartz PMFs that are shown in Vannucchi et al. are not produced by shock metamorphism.

    An enormous explosion, reportedly aerial, over Tunguska, Siberia in 1908 is commonly thought to be a bolide of some type, possibly a rocky or metallic asteroid, or an icy comet. Vannucchi et al. (2015) present a variety of arguments against the bolide hypothesis. They argue that the lack of unambiguous meteoritic material in the area excludes rocky or metallic asteroids, and that the lack of a 14C anomaly in the geoisotope record excludes a comet. They then present evidence of shock metamorphism in the area which they attribute to a volcanic superexplosion. We show here that the exclusion of a comet based on the isotopic record and the work of Liu et al. (2014) is incorrect.

    We comment on a study by Nadykto et al. recently published in this journal. Earlier work from our group has been misrepresented in this study, and we feel that the claims made need to be amended. Also the analysis of Nadykto et al. concerning the implications of their own density functional calculations is incomplete. We present cluster formation simulations allowing more conclusions to be drawn from their data, and also compare them to recent experimental results not cited in their work.

    Peng and Jing (2014) recently reported the results of hydrothermal experiments designed to produce synthetic tochilinite/cronstedtite assemblages analogous to those found in the matrix of CM chondrites (Tomeoka and Buseck, 1982, 1983a, 1983b, 1985; Mackinnon and Zolensky, 1984; Zolensky and Mackinnon, 1986; Rubin et al., 2007; Bourot-Denise et al., 2010; Hewins et al., 2014; Marrocchi et al., 2014). The assemblage was obtained from an alloyed metal particle mixture of Fe, Mg, Al, Si, Cr and Ni under basic, reducing and S2--rich conditions. The hydrothermal syntheses were conducted in Teflon-lined stainless-steel autoclaves at temperature of 106-160 °C for short-duration runs and at 153 °C for long-duration runs. The phases in the assemblage were characterized by XRD and TEM, but only the analytical results of long-duration runs were reported in the article and in the Appendix as supplementary material. The phases identified were: cronstedtite and tochilinite (both present in all run products), tochilinite-cronstedtite intergrowths, polyhedral serpentine, a chrysotile-like phase, nanotube-like structures, and lizardite-like and brucite-like phases. Based on their experimental results, the authors put forward a hypothesis to explain the formation of matrix minerals in CM chondrites proposing that the precursors may be nanometer- to micrometer-sized particles of metal alloys that were altered at low temperatures by interaction with S-rich water under reducing and dynamic pressurized conditions.

    In the cross section for single-inclusive jet production in electron-nucleon collisions, the distribution of a quark in an electron appears at next-to-next-to-leading order. The numerical calculations in Ref. [1] were carried out using a perturbative approximation for the distribution of a quark in an electron. We point out that that distribution receives nonperturbative QCD contributions that invalidate the perturbative approximation. Those nonperturbative effects enter into cross sections for hard-scattering processes through resolved-electron contributions and can be taken into account by determining the distribution of a quark in an electron phenomenologically.

    Vannucchi et al. (2015) report alleged 'shock metamorphic' features in Permian sandstone clasts associated with the Siberian Trap basalts at Mount Stojkovic inside the Great Tunguska Depression, only a few kilometers away from the site of the 1908 Tunguska event. Given the low probability that these features have formed by either the Tunguska event or by an older impact in the same area, Vannucchi et al. argue that these features may in fact not be diagnostic for impact, but could also be related to explosive volcanism.

    Perchlorate salts, recently discovered on Mars, are known to readily absorb water vapor from the atmosphere and deliquesce into the aqueous phase at room temperature. Here we study the deliquescence (crystalline solid to liquid transition) and efflorescence (liquid to crystalline solid transition) of perchlorate salts at low temperatures relevant to Mars. A Raman microscope and environmental cell were used to determine the deliquescence relative humidity (DRH) and efflorescence relative humidity (ERH) of NaClO4 and Mg(ClO4)2 as a function of temperature and hydration state. We find that the deliquescence of anhydrous NaClO4 is only slightly dependent on temperature and occurs at ∼38% RH. The DRH of NaClO4ṡH2O increases with decreasing temperature from 51% at 273 K to 64% at 228 K. The DRH of Mg(ClO4)2ṡ6H2O also increases with decreasing temperature from 42% at 273 K to 55% at 223 K. The efflorescence of both NaClO4 and Mg(ClO4)2 salt solutions occurs at a lower RH than deliquescence due to the kinetic inhibition of crystallization. For all temperatures studied, the ERH values of NaClO4 and Mg(ClO4)2 are 13% and 19%, respectively. These results indicate perchlorate salts can exist as metastable, supersaturated solutions over a wide range of RH and temperature conditions. Summer diurnal temperature and relative humidity cycles at low latitudes on Mars could allow the surface salts to be aqueous for several hours per day.

    We have found out that our evaluation of the dominant χc feed-down contributions to J / ψ + W (Subsection 5.3) was incorrect. We overlooked the fact that the α αs3 contributions via the colour-singlet transition are infrared sensitive and cannot be evaluated without that from colour-octet transitions. One should in fact compute the contributions at order α αs2 via quark-antiquark annihilation and via a 1[8]3S transition exactly as for the colour-octet contributions to the direct yield of J / ψ + W. Using = (2 J + 1) × 2 ×10-3 GeV3[1], the feed-down contribution for the ATLAS kinematical coverage (see Section 5.1 or [2]) is on the order of 0.45 fb.

    In response to inquiries from readers of the paper, we have reexamined the time series recorded at DART 32067 and confirmed the existence of a data gap in the recording between 19 and 34 min after the earthquake initiation time. The recorded time series also includes short-period ground oscillations and long-period tidal fluctuations. We originally had run the records through a script that re-sampled the data to uniform intervals and filtered out the tidal signals. This inadvertently interpolated across the data gap and distorted the signal. We misinterpreted the interpolated feature as the second arrival of the recorded tsunami in the top panel of Figs. 3e, S3e, and S4e. The recorded waveform in the corrected version of Fig. 3e appended herein has instead been de-tided using the OTIS Regional Tidal Solutions (http://volkov.oce.orst.edu/tides/PO.html).

    This paper describes a measurement of the inclusive top quark pair production cross-section (σttbar) with a data sample of 3.2 fb-1 of proton-proton collisions at a centre-of-mass energy of √{ s} = 13 TeV, collected in 2015 by the ATLAS detector at the LHC. This measurement uses events with an opposite-charge electron-muon pair in the final state. Jets containing b-quarks are tagged using an algorithm based on track impact parameters and reconstructed secondary vertices. The numbers of events with exactly one and exactly two b-tagged jets are counted and used to determine simultaneously σttbar and the efficiency to reconstruct and b-tag a jet from a top quark decay, thereby minimising the associated systematic uncertainties. The cross-section is measured to be: σttbar = 818 ± 8 (stat) ± 27 (syst) ± 19 (lumi) ± 12 (beam) pb, where the four uncertainties arise from data statistics, experimental and theoretical systematic effects, the integrated luminosity and the LHC beam energy, giving a total relative uncertainty of 4.4%. The result is consistent with theoretical QCD calculations at next-to-next-to-leading order. A fiducial measurement corresponding to the experimental acceptance of the leptons is also presented.

    K-Ar isotopic ages presented by Uysal et al. for illitic clay minerals from drill core samples were interpreted to date the Woodleigh impact event at 359±4 Ma, allegedly implicating Woodleigh in the Late Devonian mass extinction. However, only very equivocal evidence is presented by Uysal et al. to support a link between clay mineral paragenesis and impact-related features, and the K-Ar ages reveal a distribution that is essentially a continuum between 308 and 364 Ma. The 'age' computed by Uysal et al. is based on an average of the five oldest ages within this group, which has no geological or statistical basis. The stratigraphic age constraints considered by Uysal et al. to be consistent with this age are much weaker than acknowledged, and the impact could have been much older than mid-Devonian. The size of the Woodleigh crater is poorly constrained (and the subject of an ongoing controversy); Uysal et al.'s suggestion of 120 km diameter is probably overestimated by a factor of two, in which case a link to any mass extinction is unlikely.

    We introduce a two-observer all-versus-nothing proof of Bell’s theorem which reduces the number of required quantum predictions from 9 [A. Cabello, Phys. Rev. Lett. 87, 010403 (2001);PRLTAO0031-900710.1103/PhysRevLett.87.010403 Z.-B. Chen , Phys. Rev. Lett. 90, 160408 (2003)PRLTAO0031-900710.1103/PhysRevLett.90.160408] to 4, provides a greater amount of evidence against local realism, reduces the detection efficiency requirements for a conclusive experimental test of Bell’s theorem, and leads to a Bell inequality which resembles Mermin’s inequality for three observers [N. D. Mermin, Phys. Rev. Lett. 65, 1838 (1990)PRLTAO0031-900710.1103/PhysRevLett.65.1838] but requires only two observers.

    The {sup 35}Cl nuclear quadrupole resonance spectrum of a single crystal of sodium chlorate (R. Tycko, Phys. Rev. Lett. 58, 2281 (1987)) rotating about two axes reflects a non-Abelian gauge potential. This gauge potential is an example of Wilczek and Zee's (Phys. Rev.

    To celebrate the 5th anniversary of Environmental Research Letters (ERL) the publishers of the journal, IOP Publishing, have awarded a prize for the five best articles published in ERL since the journal began in 2006. The procedure for deciding the winning articles was as thorough as possible to ensure that the most outstanding articles would win the prize. A shortlist of 25 nominated research articles, five for each year since ERL was launched, which were chosen based on a range of criteria including novelty, scientific impact, readership, broad appeal and wider media coverage, was selected. The ERL Editorial Board then assessed and rated these 25 articles in order to choose a winning article for each year. We would like to announce that the following articles have been awarded ERL's 5th anniversary best article prize: 2006/7 The Bodélé depression: a single spot in the Sahara that provides most of the mineral dust to the Amazon forest Ilan Koren, Yoram J Kaufman, Richard Washington, Martin C Todd, Yinon Rudich, J Vanderlei Martins and Daniel Rosenfeld 2006 Environ.

    2006-09-01

    Two-dimensional nonequilibrium nematic steady states, as found in agitated granular-rod monolayers or films of orientable amoeboid cells, were predicted [Europhys. Lett. 62, 196 (2003)EULEEJ0295-507510.1209/epl/i2003-00346-7] to have giant number fluctuations, with the standard deviation proportional to the mean. We show numerically that the steady state of such systems is macroscopically phase separated, yet dominated by fluctuations, as in the Das-Barma model [Phys. Rev. Lett. 85, 1602 (2000)PRLTAO0031-900710.1103/PhysRevLett.85.1602]. We suggest experimental tests of our findings in granular and living-cell systems.

  12. Nonlocal distillation based on multisetting Bell inequality

    NASA Astrophysics Data System (ADS)

    Ye, Xiang-Jun; Deng, Dong-Ling; Chen, Jing-Ling

    2012-12-01

    Inspired by the recent works of Foster [Phys. Rev. Lett.0031-900710.1103/PhysRevLett.102.120401 102, 120401 (2009)] and Brunner [Phys. Rev. Lett.0031-900710.1103/PhysRevLett.102.160403 102, 160403 (2009)], we present a nonlocality distillation protocol for two three-level (qutrit) systems in the framework of generalized nonsignaling theories. Our protocol is based on a three-setting Bell inequality. It works efficiently for a specific class of three-input-three-output nonlocal boxes. In the asymptotic limit, all these nonlocal boxes can be distilled to the maximally nonlocal box defined by the inequality and nonsignaling constraints. Then we introduce a contracting protocol that reduces these boxes to the so-called “correlated nonlocal boxes.” As a result, our three-input-three-output nonlocal boxes also make communication complexity trivial and appear very unlikely to exist in nature.

We find by simulation that for a range of parameters the system is bistable: the levitated cluster can occasionally break and give rise to two clusters and a hot granular gas above and below. We use techniques from the theory of rare events to compute the mean transition time for breaking to occur. This requires the introduction of a two-component reaction coordinate.

  19. Absence of a Dirac cone in silicene on Ag(111): First-principles density functional calculations with a modified effective band structure technique

    NASA Astrophysics Data System (ADS)

    Wang, Yun-Peng; Cheng, Hai-Ping

    2013-06-01

    We investigate the currently debated issue of the existence of the Dirac cone in silicene on an Ag(111) surface, using first-principles calculations based on density functional theory to obtain the band structure. By unfolding the band structure in the Brillouin zone of a supercell to that of a primitive cell, followed by projecting onto Ag and silicene subsystems, we demonstrate that the Dirac cone in silicene on Ag(111) is destroyed. Our results clearly indicate that the linear dispersions observed in both angular-resolved photoemission spectroscopy [P. Vogt , Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.108.155501 108, 155501 (2012)] and scanning tunneling spectroscopy [L. Chen , Phys. Rev.

    We report the observation of four high-spin collective bands in ^80Sr, populated by the reaction ^58Ni(^28Si,α 2p) at 130 MeV. The data were taken with the GAMMASPHERE and MICROBALL detector arrays, the latter of which was used to select charged-particle exit channels. The characteristics of these bands will be discussed, including deduced spin assignments, measured lifetimes and Qt values. These bands are less deformed than SD bands in other Sr isotopes( D.R. LaFosse, et al., Phys. Lett. B 354) (1995) 34; C. Baktash, et al., Phys. Rev. Lett. 74 (1995) 1946; F. Cristancho, et al., Phys. Lett. B 357 (1995) 281; A.G. Smith, et al., Phys. Lett.

    Shekhter, Arkady; Modic, K. A.; McDonald, R. D.; Ramshaw, B. J.

    Magneto-quantum oscillation experiments in high-temperature superconductors show a strong thermally induced suppression of the oscillation amplitude approaching the critical dopings [B. J. Ramshaw et al., Science 348, 317 (2014), 10.1126/science.aaa4990; H. Shishido et al., Phys. Rev. Lett. 104, 057008 (2010), 10.1103/PhysRevLett.104.057008; P. Walmsley et al., Phys. Rev. Lett. 110, 257002 (2013), 10.1103/PhysRevLett.110.257002]—in support of a quantum-critical origin of their phase diagrams. We suggest that, in addition to a thermodynamic mass enhancement, these experiments may directly indicate the increasing role of quantum fluctuations that suppress the quantum oscillation amplitude through inelastic scattering. We show that the traditional theoretical approaches beyond Lifshitz-Kosevich to calculate the oscillation amplitude in correlated metals result in a contradiction with the third law of thermodynamics and suggest a way to rectify this problem.

We also include realistic parameter ranges for rubidium as the atomic species. Our results circumvent the doubts cast by recent discussion in the literature (Grangier et al Phys.

    This article emphasizes the role played by a remarkable pointwise inequality satisfied by fractionary derivatives in order to obtain maximum principles and Lp-decay of solutions of several interesting partial differential equations. In particular, there are applications to quasigeostrophic flows, in two space variables with critical viscosity, that model the Eckman pumping [see Baroud, Ch. N., Plapp, B. B., She, Z.

    We study the statistics of the vorticity field in two-dimensional Navier-Stokes turbulence with linear Ekman friction. We show that the small-scale vorticity fluctuations are intermittent, as conjectured by Bernard [Europhys. Lett. 50, 333 (2000)] and Nam et al. [Phys. Rev. Lett. 84, 5134 (2000)]. The small-scale statistics of vorticity fluctuations coincide with that of a passive scalar with finite lifetime transported by the velocity field itself.

    We study how correlations affect the performance of the simulator of a Maxwell's demon demonstrated in a recent optical experiment [M. D. Vidrighin, O. Dahlsten, M. Barbieri, M. S. Kim, V. Vedral, and I. A. Walmsley, Phys. Rev. Lett. 116, 050401 (2016), 10.1103/PhysRevLett.116.050401]. The power of the demon is found to be enhanced or hindered, depending on the nature of the correlation, in close analogy to the situation faced by a thermal demon.

    Monte Carlo simulations of (fluctuating) interfaces in Ising models confined between competing walls at temperatures above the wetting transition are presented and various correlation functions probing the interfacial fluctuation are computed. Evidence for the nonlocal interface Hamiltonian approach of A. O. Parry et al. [Phys. Rev. Lett. 93, 086104 (2004)PRLTAO0031-900710.1103/PhysRevLett.93.086104] is given. In particular, we show that two correlation lengths exist with different dependence on the distance D between the walls.

  10. Collective and single-particle excitations in two-dimensional dipolar Bose gases

    NASA Astrophysics Data System (ADS)

    Filinov, A.; Bonitz, M.

    2012-10-01

    The Berezinskii-Kosterlitz-Thouless transition in two-dimensional dipolar systems has been studied recently by path integral Monte Carlo simulations [A. Filinov , Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.105.070401 105, 070401 (2010)]. Here, we complement this analysis and study temperature-coupling strength dependence of the density (particle-hole) and single-particle (SP) excitation spectra both in superfluid and normal phases. The dynamic structure factor, S(q,ω), of the longitudinal excitations is rigorously reconstructed with full information on damping. The SP spectral function, A(q,ω), is worked out from the one-particle Matsubara Green's function. A stochastic optimization method is applied for reconstruction from imaginary times. In the superfluid regime sharp energy resonances are observed in both the density and SP excitations. The involved hybridization of both spectra is discussed. In contrast, in the normal phase, when there is no coupling, the density modes, beyond acoustic phonons, are significantly damped. Our results generalize previous zero-temperature analyses based on variational many-body wave functions [F. Mazzanti , Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.102.110405 102, 110405 (2009); D. Hufnagl , Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.107.065303 107, 065303 (2011)], where the underlying physics of the excitation spectrum and the role of the condensate has not been addressed.

    In a recent paper, Bonitz, Pehlke, and Schoof [Phys. Rev. E10.1103/PhysRevE.87.033105 87, 033105 (2013)], hereafter referred to as BPS, have raised some points against the Shukla-Eliasson attractive potential [P. K. Shukla and B. Eliasson, Phys. Rev. Lett.0031-900710.1103/PhysRevLett.108.165007 108, 165007 (2012); P. K. Shukla and B. Eliasson, Phys. Rev. Lett.0031-900710.1103/PhysRevLett.108.219902 108, 219902(E) (2012); P. K. Shukla and B.

Our objective here is to discuss the insufficiency of the BPS reasoning concerning the applicability of the linearized quantum hydrodynamic theory, as well as to point out the shortcomings in BPS’s arguments and to suggest how to salvage BPS’s density functional theory and simulations, which have failed to produce results that correctly match with that of Shukla and Eliasson.

    We theoretically study scattering process and superconducting triplet correlations in a graphene junction comprised of ferromagnet-RSO-superconductor in which RSO stands for a region with Rashba spin-orbit interaction. Our results reveal spin-polarized subgap transport through the system due to an anomalous equal-spin Andreev reflection in addition to conventional backscatterings. We calculate equal- and opposite-spin pair correlations near the F-RSO interface and demonstrate direct link of the anomalous Andreev reflection and equal-spin pairings arisen due to the proximity effect in the presence of RSO interaction. Moreover, we show that the amplitude of anomalous Andreev reflection, and thus the triplet pairings, are experimentally controllable when incorporating the influences of both tunable strain and Fermi level in the nonsuperconducting region. Our findings can be confirmed by a conductance spectroscopy experiment and may provide more insights into the proximity-induced RSO coupling in graphene layers reported recently in experiments [A. Avsar et al., Nat. Commun. 5, 4875 (2014), 10.1038/ncomms5875; Z. Wang et al., Phys. Rev. Lett. 114, 016603 (2015), 10.1103/PhysRevLett.114.016603; J. B. S. Mendes et al., Phys. Rev.

  13. Response to the comment on "Paradox of photons disconnected trajectories being located by means of `weak measurements' in the nested Mach-Zehnder interferometer" (JETP Letters 105, 152 (2017))

    In [JETP Lett. 105(3), 152 (2017)], a clear and comprehensive analysis of the paradoxical results of experiment [Phys. Rev. Lett. 111, 240402 (2013)] was carried out on the basis of the classical wave theory of light, which presupposes the continuity of possible of light paths. It was shown that the paradoxical results of the experiment are due not to the discontinuity of the trajectories of light, as claimed in [Phys. Rev. Lett. 111, 240402 (2013)], but to the used way of detecting the path of photons. The experiment modification proposed in [JETP Lett. 105(3), 152 (2017)] allows us to eliminate the seeming discontinuity of the light trajectories. In Comment [arXiv:1705.02137 (2017)] to the article such modification is declared unreasonable. This Response to the Comment shows that this statement is not based on clear and logical arguments. Instead, it is only asserted that the proposed modification "violates the faithfulness indication of the trace" of photons. Therefore, the Comment's criticism can not be considered as well-founded. Consequently, the conclusion of [JETP Lett. 105(3), 152 (2017)] that a new concept of disconnected trajectories proposed by the authors of work [Phys. Rev. Lett. 111, 240402 (2013)] is unnecessary, remains valid.

  14. Boundary-layer effects in droplet splashing

    A drop falling onto a solid substrate will disintegrate into smaller parts when its impact velocity V exceeds the so-called critical velocity for splashing, i.e., when V >V* . Under these circumstances, the very thin liquid sheet, which is ejected tangentially to the solid after the drop touches the substrate, lifts off as a consequence of the aerodynamic forces exerted on it. Subsequently, the growth of capillary instabilities breaks the toroidal rim bordering the ejecta into smaller droplets, violently ejected radially outward, provoking the splash [G. Riboux and J. M. Gordillo, Phys. Rev. Lett. 113, 024507 (2014)], 10.1103/PhysRevLett.113.024507. In this contribution, the effect of the growth of the boundary layer is included in the splash model presented in Phys. Rev. Lett. 113, 024507 (2014), 10.1103/PhysRevLett.113.024507, obtaining very good agreement between the measured and the predicted values of V* for wide ranges of liquid and gas material properties, atmospheric pressures, and substrate wettabilities. Our description also modifies the way at when the liquid sheet is first ejected, which can now be determined in a much more straightforward manner than that proposed in Phys. Rev. Lett. 113, 024507 (2014), 10.1103/PhysRevLett.113.024507.

    The relativistically induced transparency acceleration (RITA) scheme of proton and ion acceleration using laser-plasma interactions is introduced, modeled, and compared to the existing schemes. Protons are accelerated with femtosecond relativistic pulses to produce quasimonoenergetic bunches with controllable peak energy. The RITA scheme works by a relativistic laser inducing transparency [Akhiezer and Polovin, Zh. Eksp. Teor. Fiz 30, 915 (1956); Kaw and Dawson, Phys. FluidsPFLDAS0031-917110.1063/1.1692942 13, 472 (1970); Max and Perkins, Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.27.1342 27, 1342 (1971)] to densities higher than the cold-electron critical density, while the background heavy ions are stationary. The rising laser pulse creates a traveling acceleration structure at the relativistic critical density by ponderomotively [Lindl and Kaw, Phys. FluidsPFLDAS0031-917110.1063/1.1693437 14, 371 (1971); Silva , Phys. Rev. E1063-651X10.1103/PhysRevE.59.2273 59, 2273 (1999)] driving a local electron density inflation, creating an electron snowplow and a co-propagating electrostatic potential. The snowplow advances with a velocity determined by the rate of the rise of the laser's intensity envelope and the heavy-ion-plasma density gradient scale length. The rising laser is incrementally rendered transparent to higher densities such that the relativistic-electron plasma frequency is resonant with the laser frequency. In the snowplow frame, trace density protons reflect off the electrostatic potential and get snowplowed, while the heavier background ions are relatively unperturbed. Quasimonoenergetic bunches of velocity equal to twice the snowplow velocity can be obtained and tuned by controlling the snowplow velocity using laser-plasma parameters. An analytical model for the proton energy as a function of laser intensity, rise time, and plasma density gradient is developed and compared to 1D and 2D PIC OSIRIS [Fonseca , Lect. Note Comput.

    Four separate experiments [A. Etkin et al., Phys. Rev. Lett. 41, 784 (1978).][A. Etkin et al., Phys. Rev. Lett. 49, 1620 (1982).][A. Etkin et al., Phys. Lett. B 165, 217 (1985).][A. Etkin et al., Phys. Lett. B 201, 568 (1988).] observing the OZI forbidden disconnected reaction {pi}{sup -}p{yields}{phi}{phi}n with increasing statistics were consistent. These experiments, very selectively, completely broke down the OZI suppression by three {phi}{phi} resonances with I{sup G}J{sup PC}=0{sup +}2{sup ++} in the observed mass region 2.038 GeV to 2.600 GeV. The only viable proposed explanation has been that the I{sup G}J{sup PC}=0{sup +}2{sup ++} glueball expected in this mass region caused the hard glue in the disconnection to resonate and very selectively break down the OZI suppression for its quantum numbers only. Recently a pp central production spin analysis found that the f{sub 2}(1950) had a dominant decay mode f{sub 2}(1270){pi}{pi} [D. Barberis et al., Phys. Lett. B 471, 440 (2000).]). We consider if it is related to the {phi}{phi} resonances, and find that it likely is.

    As CNTs have a unique structure and remarkable physical properties, CNT composites have attracted much attention from many researchers. Especially the thermal properties of CNTs and their composite materials have been studied intensively, because CNT has very good thermal transport properties [1-5]. For example, thermal conductivity of CNT is known to be much larger than that of metals such as Ag, Au, Cu and Al. To study the thermal conductance of metal-CNT composites, we have fabricated the micro-sized suspended structures. By using e-beam lithography and metallization, two thermometers have been patterned on the GaAs substrates. Thermal links made of metal or metal-CNT composite also have been patterned between the two thermometers. Then GaAs substrate has been under-etched to form suspended structures. We will show the fabrication methods and measurement scheme using these microstructures. ^* parkyd@phya.snu.ac.kr [1] J.A. Eastman et al., Appl. Phys. Lett. 78, 718 (2001).

  18. Nature of the metastable boron-oxygen complex formation in crystalline silicon

    2010-11-01

    Transient capacitance measurements reveal new physics of metastable defect formation in boron-doped oxygen-containing crystalline silicon solar cells. These measurements demonstrate that holes are deeply trapped during defect formation and removed during thermal annealing with activation energy of 1.3 eV. Previous theoretical models {Du et al., [Phys. Rev. Lett. 97, 256602 (2006)] and Adey et al., [Phys. Rev. Lett. 93, 055504 (2004)]} are supported by present findings that defect formation is a slow two-stage process with activation energies of 0.17 eV and 0.4 eV at high and low temperature, respectively. Repulsive hole capture by a positive oxygen-dimer determines the defect formation rate at low temperature {Du et al., [Phys. Rev. Lett. 97, 256602 (2006)]}. The high temperature process is governed by a structural conversion of the dimer {Du et al., [Phys. Rev. Lett. 97, 256602 (2006)] and Adey et al., [Phys. Rev. Lett. 93, 055504 (2004)]}. An abnormally low rate prefactor allows this low-enthalpy reaction to be observed at the higher temperature. This dimer conversion presents an excellent example of an "entropy barrier" that explains the low conversion rate. Disparate formation and annealing results published here and in other publications are related by the Meyer-Neldel rule with an isokinetic temperature of 410 K.

    We study the collective modes of the fractional quantum Hall edge states using the Hamiltonian formalism [1]. While most theoretical approaches start with an effective bosonic theory [2] in which all fermions are integrated out (an exception is the approach based on Chern-Simons theory [3]), the Hamiltonian theory treats the composite fermions as fully interacting. We obtain the gapless edge-modes using a conserving approximation which respects the constraints [4]. The implications of our study to the tunneling experiments into the edge of a fractional quantum Hall system [5] are discussed. [1] R.Shankar and G.Murthy, Phys.Rev.Lett. 79, 4437 (1997).

    Slightly away from exact filling of the lowest Landau level, the quantum Hall ferromagnet contains a finite density of magnetic vortices or Skyrmions[1,2]. These Skyrmions are expected to form a square lattice[3], the low energy excitations of which (translation/phonon modes and rotation/breathing modes) lead to dramatically enhanced nuclear relaxation[4,5]. Upon changing the filling fraction, the rotational modes undergo a quantum phase transition where zero-point fluctuations destroy the orientational order of the Skyrmions[4,6]. I will discuss the effect of this quantum critical point upon nuclear spin relaxation[7]. [1]S. L. Sondhi et al., Phys. Rev. B47, 16419 (1993). [2]S. E. Barrett et al., Phys. Rev.

    20 years ago a new quantum state of matter was discovered and identified (Borovik-Romanov et al. in JETP Lett. 40:1033, 1984; 45:124, 1987; 47:478, 1988; Fomin in JETP Lett. 40:1037, 1984; Borovik-Romanov et al. in Sov.

The observed dynamic quantum state of spin precession in superfluid 3He-B bears the properties of spin current superfluidity, Bose condensation of spin waves—magnons, off-diagonal long-range order and related phenomena of quantum coherence.

  2. How to upload a physical quantum state into correlation space

    2011-04-15

    In the framework of the computational tensor network [Phys. Rev. Lett. 98, 220503 (2007)], the quantum computation is performed in a virtual linear space called the correlation space. It was recently shown [Phys. Rev. Lett. 103, 050503 (2009)] that a state in a correlation space can be downloaded to the real physical space. In this paper, conversely, we study how to upload a state from a real physical space to the correlation space. After showing the impossibility of cloning a state between a real physical space and the correlation space, we propose a simple teleportation-like method of uploading. This method also enables the Gottesman-Chuang gate teleportation trick and entanglement swapping in the virtual-real hybrid setting. Furthermore, compared with the inverse of the downloading method by Cai et al. [Phys. Rev. Lett. 103, 050503 (2009)], which also works to upload, the proposed uploading method has several advantages.

    Recently, Boyer et al. (Phys Rev Lett 99:140501, 2007) introduced a conceptually novel semi-quantum key distribution scheme (BKM07). Tan et al. (Phys Rev Lett 102:098901, 2009) showed that classical Bob is unable to detect Eve's eavesdropping by giving a special implementation of BKM07 protocol. In the reply, Boyer et al. (Phys Rev Lett 102:098902, 2009) gave a solution against the eavesdropping, i.e., Bob may place a filter that allows only photons with approximately specific frequency to pass just at the expected time . However, their improvement contradicts the descriptions about "classical." If the assumption of "classical" is not considered, we give a delay-photon Trojan-horse attack on BKM07 protocol and its improvement and further present a possible improvement.

    Gated p-n junctions in semiconducting nanotubes have recently drawn much attention for their electronic and optoelectronic characteristics [1,2,3]. We investigate the photocurrent response at a nanotube gated p-n junction using a focused laser illumination source. We find that the photocurrent at zero source-drain bias increases linearly with optical power for the component of light along the length of the nanotube. Scanned photocurrent imaging demonstrates that carrier generation occurs primarily between the p- and n- type segments of the device. Measurements in an optical cryostat down to 4K reveal large photoresponse and step-like structure in the reverse bias photocurrent. These results show that nanotube p-n junctions are highly sensitive, nanoscale photodetectors. [1] J.U. Lee et al, App. Phys. Lett. 85, 145 (2004). [2] J.U. Lee, App. Phys. Lett. 87, 073101 (2005).

    2017-01-01

    Numerical simulations in a tight-binding model have shown that an intersection of topologically protected one-dimensional chiral channels can function as a beam splitter for noninteracting fermions on a two-dimensional lattice [Qiao, Jung, and MacDonald, Nano Lett. 11, 3453 (2011), 10.1021/nl201941f; Qiao et al., Phys. Rev. Lett. 112, 206601 (2014), 10.1103/PhysRevLett.112.206601]. Here we confirm this result analytically in the corresponding continuum k .p model, by solving the associated two-dimensional Dirac equation, in the presence of a "checkerboard" potential that provides a right-angled intersection between two zero-line modes. The method by which we obtain our analytical solutions is systematic and potentially generalizable to similar problems involving intersections of one-dimensional systems.

    The effect of Compton scattering on the ratio of double-to-single ionization from photon impact in helium has been measured for 2.1<=hν<=5.5 keV using a time-of-flight ion spectrometer with a high relative collection efficiency for Compton ions. Single ionization from Compton scattering is found to contribute measurably to a reduction in the ionization ratio for hν>~3.5 keV. Our measurements are compared with predictions based on recent calculations of the single and double ionization cross sections for photoabsorption and Compton scattering by Hino et al. [Phys. Rev. A 48, 1271 (1993), Phys. Rev. Lett. 72, 1620 (1994)], Andersson et al. [Phys. Rev. Lett. 71, 50 (1993)], and Surić et al. [Phys. Rev. Lett. 73, 790 (1994)].

    High intensity, short pulse lasers can be used to accelerate electrons to ultra-relativistic energies via laser wakefield acceleration (LWFA) [T. Tajima and J. M. Dawson, Phys. Rev.

Although the measured energy splittings between pseudospin doublets are small, the eigenfunctions of the doublets have been examined only recently [3]. We show to what extent the pseudospin partners of realistic relativistic mean field eigenfunctions [4] are themselves eigenfunctions of the same Dirac Hamiltonian. 1) J. N. Ginocchio, Phys. Rev.

    We deal here with the issue of determinism versus randomness in time series (TS), with the goal of identifying their relative importance in a given TS. To this end we extend (i) the use of ordinal patterns based probability distribution functions associated to a TS [C. Bandt and B. Pompe, Phys. Rev.

Useful information on the deterministic component of the original time series is obtained with the help of the so-called causal entropy-complexity plane [O.A. Rosso et al., Phys. Rev.

The data are compared with the theories of Pirč et al (2009 Phys. Rev. B 79 214114), Parish and Littlewood (2008 Phys. Rev. Lett. 101 166602) and Catalan (2006 Appl. Phys. Lett. 88 102902). The results are interpreted as due not to magnetocapacitance but to the sharp negative magnetoresistance in LSMO at low magnetic fields (Hwang et al 1996 Phys. Rev. Lett. 77 2041), which causes a dramatic increase in leakage current through the PZT.

    The time-reversal Aharonov-Casher (AC) [Phys. Rev. Lett. 53, 319 (1984)] interference effect in the mesoscopic ring structures, based on the experiment in Phys. Rev. Lett. 97, 196803 (2006), is studied theoretically. The transmission curves are calculated from the scattering matrix formalism, and the time-reversal AC interference frequency is singled out from the Fourier spectra in numerical simulations. This frequency is in good agreement with analytical result. It is also shown that in the absence of magnetic field, the Altshuler-Aronov-Spivak type [JETP Lett. 33, 94 (1981)] (time reversal) AC interference is retained under the influence of strong disorder, while the Aharonov-Bohm type [Phys. Rev. 115, 485 (1959)] AC interference is suppressed.

    We assess the performance of nonempirical, truly nonlocal, and semilocal functionals with regard to structural and thermal properties of 3 d ,4 d , and 5 d nonmagnetic transition metals. We focus on constraint- based functionals and consider the consistent-exchange van der Waals density-functional version vdW-DF-cx [Phys. Rev. B 89, 035412 (2014), 10.1103/PhysRevB.89.035412], the semilocal PBE functional [Phys. Rev. Lett. 77, 3865 (1996), 10.1103/PhysRevLett.77.3865], and the PBEsol functional [Phys. Rev. Lett. 100, 136406 (2008), 10.1103/PhysRevLett.100.136406], as well as the AM05 metafunctional [Phys. Rev. B 72, 085108 (2005), 10.1103/PhysRevB.72.085108]. Using the quasiharmonic approximation, the structural parameters, elastic response, and thermal expansion at finite temperatures are computed and compared to experimental data. We also compute cohesive energies explicitly including zero-point vibrations. It is shown that overall vdW-DF-cx provides an accurate description of thermal properties and retains a level of transferability and accuracy that is comparable to or better than some of the best constraint-based semilocal functionals. Especially, with regard to the cohesive energies, the consistent inclusion of spin-polarization effects in the atoms turns out to be crucial, and it is important to use the rigorous spin-vdW-DF-cx formulation [Phys. Rev. Lett. 115, 136402 (2015), 10.1103/PhysRevLett.115.136402]. This demonstrates that vdW-DF-cx has general-purpose character and can be used to study systems that have both sparse and dense electron distributions.

    The gyromagnetic factor is an important physical quantity relating the magnetic-dipole moment of a particle to its spin. The electron spin g -factor in vacuo is one of the best model-based theoretical predictions ever made, showing agreement with the measured value up to ten parts per trillion [J. Schwinger, Phys. Rev. 73, 416 (1948), 10.1103/PhysRev.73.416; R. S. Van Dyck, Jr. et al., Phys. Rev. Lett. 59, 26 (1987), 10.1103/PhysRevLett.59.26; D. Hanneke et al., Phys. Rev. Lett. 100, 120801 (2008), 10.1103/PhysRevLett.100.120801; T. Aoyama et al., Phys. Rev. Lett. 109, 111807 (2012), 10.1103/PhysRevLett.109.111807]. However, for electrons in a material the g -factor is modified with respect to its value in vacuo because of environment interactions. Here, we show how interaction effects lead to the spin g -factor correction in graphene by considering the full electromagnetic interaction in the framework of pseudo-QED [A. Kovner et al., Phys. Rev. B 42, 4748 (1990), 10.1103/PhysRevB.42.4748; N. Dorey et al., Nucl. Phys. B 386, 614 (1992), 10.1016/0550-3213(92)90632-L; S. Teber, Phys. Rev. D 86, 025005 (2012), 10.1103/PhysRevD.86.025005; S. Teber, Phys. Rev. D 89, 067702 (2014), 10.1103/PhysRevD.89.067702; E. C. Marino, Nucl. Phys. B 408, 551 (1993), 10.1016/0550-3213(93)90379-4]. We compare our theoretical prediction with experiments performed on graphene deposited on SiO2 and SiC, and we find a very good agreement between them.

    An improvement of the scheme by Brunner and Simon [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.105.010405 105, 010405 (2010)] is proposed in order to show that quantum weak measurements can provide a method to detect ultrasmall longitudinal phase shifts, even with white light. By performing an analysis in the frequency domain, we find that the amplification effect will work as long as the spectrum is large enough, irrespective of the behavior in the time domain. As such, the previous scheme can be notably simplified for experimental implementations.

    Phys. Rev. Lett. 89, 026401 (2002)PRLTAO0031-900710.1103/PhysRevLett.89.026401

    The four-state continuous-variable quantum key distribution protocol has a long practical secure distance [A. Leverrier and P. Grangier, Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.102.180504 102, 180504 (2009)], while it poses the difficulty of parameter estimation. We propose an improved four-state protocol where the covariance matrix can be estimated from experimental data without using the linear channel assumption, thus ensuring its unconditional security in the asymptotical limit. Our scheme maintains the advantage of high reconciliation efficiency of the four-state protocol, which ensures long practical secure distance its. Our scheme can be implemented with the current technology.

    We reexamine the topological and nonlocal natures of the Aharonov-Casher and scalar Aharonov-Bohm phase effects. The underlying U(1) gauge structure is exhibited explicitly. And the conditions for developing topological Aharonov-Casher and scalar Aharonov-Bohm phases are clarified. We analyze the arguments of M. Peshkin and H. J. Lipkin [Phys. Rev. Lett. 74, 2847 (1995)PRLTAO0031-900710.1103/PhysRevLett.74.2847] in detail and show that they are based on the wrong Hamiltonian which yields their conclusion incorrect.

    In this Comment we point out (i) that the Hamiltonian, Eq. (17) in the Letter(Phys. Rev. Lett. 108, 070405 (2012)), is not a relativistic Hamiltonian, (ii) then that the conditions in the Letter are irrelevant for a topological AC and SAB effects, and (iii) conclusively that the non-relativistic Hamiltonian employed by Peshkin and Lipkin (Phys. Rev. Lett. 74, 2847 (1995)) has the same $U(1)_{mm}$ gauge structure for a fixed spin and then is not wrong, but their incorrect interpretation of the spin autocorrelations led to the incorrect conclusion.

    In a recent Letter [P. K. Shukla and B. Eliasson, Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.108.165007 108, 165007 (2012)] the discovery of a new attractive force between protons in a hydrogen plasma was reported that would be responsible for the formation of molecules and of a proton lattice. Here we show, based on ab initio density functional calculations and general considerations, that these predictions are not correct and caused by using linearized quantum hydrodynamics beyond the limits of its applicability.

    Based on the assumption of weak dissipation introduced by Esposito [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.105.150603 105, 150603 (2010)], analytic expressions for the efficiency bounds of several classes of typical thermodynamic cycles at the maximum power output are derived. The results obtained are of universal significance. They can be used to conveniently reveal the general characteristics of not only Carnot heat engines, but also isothermal chemical engines, non-Carnot heat engines, flux flow engines, gravitational engines, quantum Carnot heat engines, and two-level quantum Carnot engines at the maximum power output and to directly draw many important conclusions in the literature.

    We extend our previous application of the convergent close-coupling (CCC) and time-dependent close-coupling (TDCC) methods [Phys. Rev. A10.1103/PhysRevA.81.023418 81, 023418 (2010)] to describe energy and angular resolved double photoionization (DPI) of lithium at arbitrary energy sharing. By doing so, we are able to evaluate the recoil ion momentum distribution of DPI of Li and make a comparison with recent measurements of Zhu [Phys. Rev.

    Single-photon laser-enabled Auger decay (spLEAD) is predicted theoretically [B. Cooper and V. Averbukh, Phys. Rev. Lett. 111, 083004 (2013), 10.1103/PhysRevLett.111.083004] and here we report its first experimental observation in neon. Using coherent, bichromatic free-electron laser pulses, we detect the process and coherently control the angular distribution of the emitted electrons by varying the phase difference between the two laser fields. Since spLEAD is highly sensitive to electron correlation, this is a promising method for probing both correlation and ultrafast hole migration in more complex systems.

    We determine and analyze the quantum phases and time delays in photoionization and photorecombination of valence 3 p and 3 s electrons of argon using the Kohn-Sham local-density-functional approach. The time-dependent local-density approximation is used to account for the electron correlation. Resulting attosecond Wigner-Smith time delays show very good agreement with the recent experiment on argon that measured the delay in 3 p photorecombination [S. B. Schoun et al., Phys. Rev.

    2011-02-01

    A new hybrid inflationary scenario in the context of f(R,□R)-gravity is proposed. Demanding the waterfall field to 'support the potential from below' [unlike the original proposal by Stewart in Phys. Lett. B 345, 414 (1995)], we demonstrate that the scalar potential is similar to that of the large-field chaotic inflation model proposed by Linde in Phys. Lett. B 129, 177 (1983). Inflationary observables are used to constrain the parameter space of our model; in the process, an interesting limit on the number of e-folds N is found.

    We derive backward and forward fractional Feynman-Kac equations for the distribution of functionals of the path of a particle undergoing anomalous diffusion. Fractional substantial derivatives introduced by Friedrich and co-workers [Phys. Rev. Lett. 96, 230601 (2006)10.1103/PhysRevLett.96.230601] provide the correct fractional framework for the problem. For applications, we calculate the distribution of occupation times in half space and show how the statistics of anomalous functionals is related to weak ergodicity breaking.

    2014-03-01

    We numerically simulate the creation process of two-dimensional skyrmionic excitations in antiferromagnetic spin-1 Bose-Einstein condensates by solving the full three-dimensional dynamics of the system from the Gross-Pitaevskii equation. Our simulations reproduce quantitatively the experimental results of Choi et al. [Phys. Rev. Lett. 108, 035301 (2012), 10.1103/PhysRevLett.108.035301] without any fitting parameters. Furthermore, we examine the stability of the skyrmion by computing the temporal evolution of the condensate in a harmonic potential. The presence of both the quadratic Zeeman effect and dissipation in the simulations is vital for reproducing the experimentally observed decay time.

    2004-12-01

    Experiments on the quantitative determination of the ion drag force on free-falling dust particles in a collisionless regime are presented. The ion drag forces are measured for ion energies up to 40 eV and the obtained results are compared in detail with theories. Good agreement is found with the Barnes model [Barnes et al., Phys. Rev. Lett. 68, 313 (1992)] of the ion drag force for high ion energies (E>3 eV). At lower ion energies the model of Khrapak [Khrapak et al., Phys. Rev. Lett. 90, 225002 (2003)] is found to give a better description of the capture of slowly streaming ions by highly charged particles.

    Recent investigations have reported on the synchronization of the output of coupled chaotic systems(G. L. Baker, J. A. Blackburn, & H. J. T. Smith, Phys. Rev. Lett. 81), 554 (1998).. We have reported on the control of chaotic pattern dynamics in Taylor Vortex Flow by proportional feedback of a system parameter(R. J. Wiener, et al., Phys. Rev. Lett. 83), 2340 (1999).. We perform numerical investigations seeking to control coupled chaotic pendula in a regime which displays synchronization. We report the results of these numerical studies and comment on the prospects for experimental attempts to control coupled regions of super-critical Taylor Vortex Flow.

    The intriguing difference between far-infrared photoconductivity spectroscopy and absorption spectroscopy in the measurement of the magnetoplasmon frequency in GaAs quantum wells reported by Holland et al. [Phys. Rev. Lett. 93, 186804 (2004)] remains unexplained to date. This Letter provides a consistent mechanism to solve this puzzle. The mechanism is based on the electron reservoir model for the integer quantum Hall effect in graphene [Phys. Lett. A 376, 616 (2012)]. We predict sharp kinks to appear in the magnetic induction dependence of the magnetoplasmon frequency at very low temperatures such as 14 mK in the same GaAs quantum well sample used by Holland et al..

    The study of the antiproton ( bar {p}) annihilation cross section on nuclei at low energies (eV-MeV region) has implications for fundamental cosmology as well as for nuclear physics. Concerning the former, different models try to explain the matter/antimatter asymmetry in the universe assuming the existence of the so-called "islands" where antinucleon-nucleon annihilations occur in the border region (Cohen et al. Astrophys. J. 495, 539-549, 1998), while, from the nuclear physics point of view, the annihilation process is a valuable tool to evaluate the neutron/proton ratio in order to probe the external region of the nucleus (Gupta et al. Nucl. Phys. B 70(3), 414-424, 1974). The existing data of antinucleon-nucleon (or -nucleus) annihilation cross-sections are mainly confined to energies above ≈1 MeV, while the cross section measured at LEAR in the 80's-90's (mostly with light targets Agnello et al. Phys. Lett. B 256, 349-353, 1991; Bertin et al. Phys. Lett. B 369, 77-85, 1996; Bertin et al. Phys. Lett. B 414, 220-228, 1997; Zenoni et al. Phys. Lett. B 461, 405-412, 1999; Bianconi et al. Phys. Lett. B 481, 194-198, 2000; Bianconi et al. Phys. Lett. B 492, 254-258, 2000) showed an unexpected behaviour for energies below 1 MeV (Bianconi et al. Phys. Lett. B 483, 353-359, 2000; Bianconi et al. Phys. Rev. C 62, 014611-7, 2000; Batty et al. Nucl. Phys. A 689, 721-740, 2001). The results showed a saturation with the atomic mass number against the A 2/3 trend which is observed for higher energies (being A the target mass number). The ASACUSA collaboration at CERN recently measured antiproton annihilation cross section on different kinds of nuclei with a bar {p} kinetic energy of 5.3 MeV (Bianconi et al. Phys. Lett. B 704, 461-466, 2011; Corradini et al. Nucl. Instr. Methods A 711, 12-20, 2013). Such results proved compatibility with the black-disk model with the Coulomb correction. But till now experimental difficulties prevented the investigation at energies below ≈1

    NASA Astrophysics Data System (ADS)

    Namiki, Ryo; Jiang, Liang; Kim, Jungsang; Lütkenhaus, Norbert

    2016-11-01

    We investigate a quantum repeater scheme for quantum key distribution based on the work by S. Muralidharan et al. [Phys. Rev. Lett. 112, 250501 (2014)], 10.1103/PhysRevLett.112.250501. Our scheme extends that work by making use of error syndrome measurement outcomes available at the repeater stations. We show how to calculate the secret key rates for the case of optimizing the syndrome information, while the known key rate is based on a scenario of coarse graining the syndrome information. We show that these key rates can surpass the Pirandola-Laurenza-Ottaviani-Banchi bound on secret key rates of direct transmission over lossy bosonic channels.

    Following Marx et al. [Phys. Rev. Lett. 111, 243007 (2013), 10.1103/PhysRevLett.111.243007], we discuss the measurement and manipulation of the temperature of cold CO molecules in a microchip environment. In particular, we present a model to explain the observed and calculated velocity distributions. We also show that a translational temperature can be extracted directly from the measurements. Finally, we discuss the conditions needed for an effective adiabatic cooling of the molecular ensemble trapped on the microchip.

    We conjecture a new entropic uncertainty principle governing the entropy of complementary observations made on a system given side information in the form of quantum states, generalizing the entropic uncertainty relation of Maassen and Uffink [Phys. Rev. Lett. 60, 1103 (1988)PRLTAO0031-900710.1103/PhysRevLett.60.1103]. We prove a special case for certain conjugate observables by adapting a similar result found by Christandl and Winter pertaining to quantum channels [IEEE Trans. Inf. Theory 51, 3159 (2005)IETTAW0018-944810.1109/TIT.2005.853338], and discuss possible applications of this result to the decoupling of quantum systems and for security analysis in quantum cryptography.

    We study the time evolution of the optical spin Hall effect, which occurs when exciton polaritons undergo resonant Rayleigh scattering. The resulting spin pattern in momentum space is quantified by calculating the degree of circular polarization of the momentum space image for each point in time. We find the degree of circular polarization performing oscillations, which can be described within the framework of the pseudospin model by Kavokin et al. [A. Kavokin, G. Malpuech, and M. Glazov, Phys. Rev. Lett. 95, 136601 (2005), 10.1103/PhysRevLett.95.136601].

Transient effects are also identified.

    2016-02-01

    We develop a Gaussian state treatment that allows a transparent quantum description of the continuous, nondestructive imaging of and feedback on a Bose-Einstein condensate. We have previously demonstrated [A. C. J. Wade et al., Phys. Rev. Lett. 115, 060401 (2015), 10.1103/PhysRevLett.115.060401] that the measurement backaction of stroboscopic imaging leads to selective squeezing and entanglement of quantized density oscillations. Here, we investigate how the squeezing and entanglement are affected by the finite spatial resolution and geometry of the probe laser beam and of the detector and how they can be optimized.

    2006-08-25

    Quantum well (QW) resonances in Fe(001)/MgO/Fe/MgO/Fe double barrier magnetic tunnel junctions are calculated from first principles. By including the Coulomb blockade energy due to the finite size islands of the middle Fe film, we confirm that the oscillatory differential resistance observed in a recent experiment [T. Nozaki, Phys. Rev. Lett. 96, 027208 (2006)10.1103/PhysRevLett.96.027208] originates from the QW resonances from the Delta1 band of the Fe majority-spin channel. The primary source of smearing at low temperatures is shown to be the variation of the Coulomb blockade energy.

    We report on the experimental observation of novel defect-free surface modes predicted theoretically for modulated photonic lattices [I. L. Garanovich et al., Phys. Rev. Lett. 100, 203904 (2008)PRLTAO0031-900710.1103/PhysRevLett.100.203904]. We generate the linear surface modes in truncated arrays of periodically curved optical waveguides created in fused silica by a laser direct-writing technique. Our results demonstrate that the degree of surface wave localization can be controlled by selecting the waveguide bending amplitude.

    1997-03-01

    The steady-state properties of a dye laser model with white quantum noise and strongly colored pump noise are investigated. An effective diffusion coefficient in the steady state is presented. Our coefficient differs from that of Fox and Roy [Phys. Rev. A 35, 1838 (1987)]. We compare our results with the measurements and simulations of Lett, Short, and Mandel [Phys. Rev. Lett. 52, 341 (1984)], and the results of Fox and Roy, respectively. We find that the quantum noise plays an important role in the steady-state analysis of laser fluctuations below and near threshold.

    A head-on beam-beam compensation scheme was implemented for operation in the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory [Phys. Rev. Lett. 115, 264801 (2015), 10.1103/PhysRevLett.115.264801]. The compensation consists of electron lenses for the reduction of the beam-beam induced tune spread, and a lattice for the minimization of beam-beam generated resonance driving terms. We describe the implementations of the lattice and electron lenses, and report on measurements of lattice properties and the effect of the electron lenses on the hadron beam.

    2015-10-01

    An interconnected network features a structural transition between two regimes [F. Radicchi and A. Arenas, Nat. Phys. 9, 717 (2013), 10.1038/nphys2761]: one where the network components are structurally distinguishable and one where the interconnected network functions as a whole. Our exact solution for the coupling threshold uncovers network topologies with unexpected behaviors. Specifically, we show conditions that superdiffusion, introduced by Gómez et al. [Phys. Rev. Lett. 110, 028701 (2013), 10.1103/PhysRevLett.110.028701], can occur despite the network components functioning distinctly. Moreover, we find that components of certain interconnected network topologies are indistinguishable despite very weak coupling between them.

    We develop models for the propagation of intense pulses in solid state media which can have either saturated absorption or reverse absorption. We model subluminal propagation in ruby and superluminal propagation in alexandrite as three and four level systems, respectively, coupled to Maxwell's equations. We present results well beyond the traditional pump-probe approach and explain the experiments of Bigelow et al. [

    Xu, Zhen-Peng; Saha, Debashis; Su, Hong-Yi; Pawłowski, Marcin; Chen, Jing-Ling

    2016-12-01

    A new theory-independent noncontextuality inequality is presented [R. Kunjwal and R. W. Spekkens, Phys. Rev. Lett. 115, 110403 (2015), 10.1103/PhysRevLett.115.110403] based on a Kochen-Specker (KS) set without imposing the assumption of determinism. By proposing noncontextuality inequalities, we show that such result can be generalized from a KS set to the noncontextuality inequalities not only for a state-independent scenario but also for a state-dependent scenario. The YO-13 ray and n cycle ray are considered as examples.

  15. Effects of thin film and Stokes drift on the generation of vorticity by surface waves

    NASA Astrophysics Data System (ADS)

    Parfenyev, V. M.; Vergeles, S. S.; Lebedev, V. V.

    2016-11-01

    Recently a theoretical scheme explaining the vorticity generation by surface waves in liquids was developed [Phys. Rev. Lett. 116, 054501 (2016), 10.1103/PhysRevLett.116.054501]. Here we study how a thin (monomolecular) film presented on the surface of liquid affects the generated vorticity. We demonstrate that the vorticity becomes parametrically larger than for the case of liquid with a free surface, and the parameter is the quality factor of surface waves up to numerical factor. We also discuss the PIV experimental scheme intended to observe the generated vorticity and find that Stokes drift influences the measured velocity field. Explicit expression for the vertical vorticity was obtained.

    We present a derivation of generalized Poisson-Boltzmann equations starting from classical theories of binary fluid mixtures, employing an approach based on the Legendre transform as recently applied to the case of local descriptions of the fluid free energy. Under specific symmetry assumptions, and in the linearized regime, the Poisson-Boltzmann equation reduces to a phenomenological equation introduced by Bazant et al. [Phys. Rev. Lett. 106, 046102 (2011)]PRLTAO0031-900710.1103/PhysRevLett.106.046102, whereby the structuring near the surface is determined by bulk coefficients.

    The quantum adiabatic theorem plays an important role in quantum mechanics. However, counter-examples were produced recently, indicating that their transition probabilities do not converge as predicted by the adiabatic theorem [K. P. Marzlin et al., Phys. Rev. Lett. 93, 160408 (2004); D. M. Tong et al., Phys. Rev. Lett. 95, 110407 (2005)]. For a special class of Hamiltonians, we examine the standard criterion for adiabatic evolution experimentally and theoretically, as well as three newly suggested adiabatic conditions. We show that the standard criterion is neither sufficient nor necessary.

    2016-11-01

    In the year 2013, Danan et al. published a paper [Phys. Rev. Lett. 111, 240402 (2013), 10.1103/PhysRevLett.111.240402] demonstrating a counterintuitive behavior of photons in nested Mach-Zehnder interferometers. The authors then proposed an explanation based on the two-state vector formalism. This experiment and the authors' explanation raised a vivid debate within the scientific community. In this paper, we contribute to the ongoing debate by presenting an alternative experimental implementation of the Danan et al. scheme. We show that no counterintuitive behavior is observed when performing direct spectrally resolved detection.

    2008-09-19

    An 60Fe peak in a deep-sea FeMn crust has been interpreted as due to the signature left by the ejecta of a supernova explosion close to the solar system 2.8+/-0.4 Myr ago [Knie, Phys. Rev. Lett. 93, 171103 (2004)10.1103/PhysRevLett.93.171103]. In an attempt to confirm this interpretation with better time resolution and obtain a more direct flux estimate, we measured 60Fe concentrations along a dated marine sediment. We find no 60Fe peak at the expected level from 1.7 to 3.2 Myr ago. Possible causes for the discrepancy are discussed.

    We experimentally demonstrate the strictly nonclassical behavior in a many-atom system using a recently derived criterion [E. Kot et al., Phys. Rev. Lett. 108, 233601 (2012), 10.1103/PhysRevLett.108.233601] that explicitly does not make use of quantum mechanics. We thereby show that the magnetic-moment distribution measured by McConnell et al. [Nature (London) 519, 439 (2015), 10.1038/nature14293] in a system with a total mass of 2.6 ×105 atomic mass units is inconsistent with classical physics. Notably, the strictly nonclassical behavior affects an area in phase space 103 times larger than the Planck quantum ℏ .

We reproduce the result obtained using nonrelativistic quantum mechanics by Meißner et al. in [Phys. Rev.

    Peiponen et al. [Opt. Lett.35, 4108 (2010)] have expressed concern that a theoretical model we proposed in Calhoun et al. [Opt. Lett.35, 1224 (2010)] for total internal reflection from a turbid medium may be inconsistent with the experimental data, in the sense that the model fails to take into account unexplained oscillations in our data. We show that their concern arises from misinterpretation of our data and theory, and is, therefore, unfounded.

    We study quantum phase transitions in non-Hermitian XY and transverse-field Ising spin chains, in which the non-Hermiticity arises from the imaginary magnetic field. Analytical and numerical results show that at exceptional points, coalescing eigenstates in these models are close to W, distant Bell, and GHZ states, which can be steady states in the dynamical preparation scheme proposed by Lee et al. [T. E. Lee et al., Phys. Rev. Lett. 113, 250401 (2014), 10.1103/PhysRevLett.113.250401]. By selecting proper initial states, numerical simulations demonstrate the time evolution process to the target states with high fidelity.

They showed that a set of measurements is incompatible (i.e., not jointly measurable) if and only if it can be used for the demonstration of steering. In this paper, we prove the temporal analog of this result viz., a set of measurements are incompatible if and only if it exhibits temporal steering.

    We theoretically investigate the confinement-induced resonance for quasi-one-dimensional quantum systems under transversely anisotropic confinement, using a two-body s-wave-scattering model in the zero-energy collision limit. We predict a single resonance for any transverse anisotropy, whose position shows a slight downshift with increasing anisotropy. We compare our prediction with the recent experimental result by Haller [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.104.153203 104, 153203 (2010)], in which two resonances are observed in the presence of transverse anisotropy. The discrepancy between theory and experiment remains to be resolved.

    We consider the interaction of Rydberg atoms with strong infrared laser pulses using an approach based on the Magnus expansion of the time evolution operator. First-order corrections beyond the electric dipole approximation are also included in the theory. We illustrate the dynamics of the interaction at the parameters of the experiment [Eichmann et al., Phys. Rev. Lett. 110, 203002 (2013), 10.1103/PhysRevLett.110.203002]. It emerges that the depletion of Rydberg atoms in this regime comes predominantly from the nondipole effects.

    It is shown that the use of a high power alpha of the Laplacian in the dissipative term of hydrodynamical equations leads asymptotically to truncated inviscid conservative dynamics with a finite range of spatial Fourier modes. Those at large wave numbers thermalize, whereas modes at small wave numbers obey ordinary viscous dynamics [C. Cichowlas et al., Phys. Rev. Lett. 95, 264502 (2005)10.1103/Phys. Rev. Lett. 95.264502]. The energy bottleneck observed for finite alpha may be interpreted as incomplete thermalization. Artifacts arising from models with alpha>1 are discussed.

    We demonstrate that the compositional sensitivity of an atomic force microscope is enhanced by the simultaneous excitation of its first two normal eigenmodes^1-2. The coupling of those modes by the non-linear probe-surface interactions enables to map compositional changes in several conjugated molecular materials with a phase shift sensitivity that is about two orders of magnitude higher than the one achieved in amplitude modulation atomic force microscopy. *T.R.

  5. Generality of Deterministic Chaos, Exponential Spectra, and Lorentzian Pulses in Magnetically Confined Plasmas

    The dynamics of transport at the edge of magnetized plasmas is deterministic chaos. The connection is made by a previous survey [M. A. Pedrosa , Phys. Rev. Lett. 82, 3621 (1999)PRLTAO0031-900710.1103/PhysRevLett.82.3621] of measurements of fluctuations that is shown to exhibit power spectra with exponential frequency dependence over a broad range, which is the signature of deterministic chaos. The exponential character arises from Lorentzian pulses. The results suggest that the generalization to complex times used in studies of deterministic chaos is a representation of Lorentzian pulses emerging from the chaotic dynamics.

    We show two experimental realizations of Hardy’s ladder test of quantum nonlocality using energy-time correlated photons, following the scheme proposed by Cabello [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.102.040401 102, 040401 (2009)]. Unlike previous energy-time Bell experiments, these tests require precisely tailored nonmaximally entangled states. One of them is equivalent to the two-setting and two-outcome Bell test requiring a minimum detection efficiency. The reported experiments are still affected by the locality and detection loopholes, but are free of the post-selection loophole of previous energy-time and time-bin Bell tests.

    We report a state-independent experimental test of quantum contextuality of a single-photon qutrit. The experimental results demonstrate violations of an inequality originally formulated by Yu and Oh [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.108.030402 108, 030402 (2012)] and further optimized by Cabello [Phys. Rev. APLRAAN1050-294710.1103/PhysRevA.85.032108 85, 032108 (2012)]; this inequality is satisfied by all noncontextual hidden variable models and is violated by all qutrit states. Our experiment shows quantum contextuality of this nature in a most fundamental way: A way that is independent of state and unrelated to entanglement.

    The correlations between two qubits belonging to a three-qubit system can violate the Clauser-Horne-Shimony-Holt-Bell inequality beyond Tsirelson’s bound [A. Cabello, Phys. Rev. Lett. 88, 060403 (2002)PRLTAO0031-900710.1103/PhysRevLett.88.060403]. We experimentally demonstrate such a violation by 7 standard deviations by using a three-photon polarization-entangled Greenberger-Horne-Zeilinger state produced by Type-II spontaneous parametric down-conversion. In addition, using part of our results, we obtain a violation of the Mermin inequality by 39 standard deviations.

    We performed an experimental test of the Kochen-Specker theorem based on an inequality derived from the Peres-Mermin proof, using spin-path (momentum) entanglement in a single neutron system. Following the strategy proposed by Cabello et al. [Phys. Rev. Lett. 100, 130404 (2008)PRLTAO0031-900710.1103/PhysRevLett.100.130404], a Bell-like state was generated, and three expectation values were determined. The observed violation 2.291±0.008≰1 clearly shows that quantum mechanical predictions cannot be reproduced by noncontextual hidden-variable theories.

  14. Partial coherence with application to the monotonicity problem of coherence involving skew information

    NASA Astrophysics Data System (ADS)

    Luo, Shunlong; Sun, Yuan

    2017-08-01

    Quantifications of coherence are intensively studied in the context of completely decoherent operations (i.e., von Neuamnn measurements, or equivalently, orthonormal bases) in recent years. Here we investigate partial coherence (i.e., coherence in the context of partially decoherent operations such as Lüders measurements). A bona fide measure of partial coherence is introduced. As an application, we address the monotonicity problem of K -coherence (a quantifier for coherence in terms of Wigner-Yanase skew information) [Girolami, Phys. Rev. Lett. 113, 170401 (2014), 10.1103/PhysRevLett.113.170401], which is introduced to realize a measure of coherence as axiomatized by Baumgratz, Cramer, and Plenio [Phys. Rev. Lett. 113, 140401 (2014), 10.1103/PhysRevLett.113.140401]. Since K -coherence fails to meet the necessary requirement of monotonicity under incoherent operations, it is desirable to remedy this monotonicity problem. We show that if we modify the original measure by taking skew information with respect to the spectral decomposition of an observable, rather than the observable itself, as a measure of coherence, then the problem disappears, and the resultant coherence measure satisfies the monotonicity. Some concrete examples are discussed and related open issues are indicated.

    2017-02-01

    We study the set of almost-quantum correlations and their refinements in the simplest tripartite Bell scenario where each party is allowed to perform two dichotomic measurements. In contrast to its bipartite counterpart, we find that there already exist facet Bell inequalities that witness almost-quantum correlations beyond quantum theory in this simplest tripartite Bell scenario. Furthermore, we study the relation between the almost-quantum set and the hierarchy of supersets to the quantum set due to Navascués-Pironio-Acín (NPA) [Phys. Rev. Lett. 98, 010401 (2007), 10.1103/PhysRevLett.98.010401]. While the former lies between the first and the third level of the NPA hierarchy, we find that its second level does not contain and is not contained within the almost-quantum set. Finally, we investigate the hierarchy of refinements to the almost-quantum set due to Moroder et al. [Phys. Rev. Lett. 111, 030501 (2013), 10.1103/PhysRevLett.111.030501], which converges to the set of quantum correlations producible by quantum states having positive partial transposition. This allows us to consider (approximations of) the "biseparable" subsets of the almost-quantum set as well as of the quantum set of correlations, and thereby gain further insights into the subtle similarities and differences between the two sets. In addition, they allow us to identify candidate Bell-like inequalities that can serve as device-independent witnesses for genuine tripartite entanglement.

    NASA Astrophysics Data System (ADS)

    Martiniani, Stefano; Schrenk, K. Julian; Stevenson, Jacob D.; Wales, David J.; Frenkel, Daan

    2016-01-01

    We present a numerical calculation of the total number of disordered jammed configurations Ω of N repulsive, three-dimensional spheres in a fixed volume V . To make these calculations tractable, we increase the computational efficiency of the approach of Xu et al. [Phys. Rev. Lett. 106, 245502 (2011), 10.1103/PhysRevLett.106.245502] and Asenjo et al. [Phys. Rev. Lett. 112, 098002 (2014), 10.1103/PhysRevLett.112.098002] and we extend the method to allow computation of the configurational entropy as a function of pressure. The approach that we use computes the configurational entropy by sampling the absolute volume of basins of attraction of the stable packings in the potential energy landscape. We find a surprisingly strong correlation between the pressure of a configuration and the volume of its basin of attraction in the potential energy landscape. This relation is well described by a power law. Our methodology to compute the number of minima in the potential energy landscape should be applicable to a wide range of other enumeration problems in statistical physics, string theory, cosmology, and machine learning that aim to find the distribution of the extrema of a scalar cost function that depends on many degrees of freedom.

    Dietrich, Tim; Hinderer, Tanja

    2017-06-01

    We present a detailed comparison between tidal effective-one-body (EOB) models and new state-of-the-art numerical relativity simulations for nonspinning binary neutron star systems. This comparison is the most extensive one to date, covering a wide range in the parameter space and encompassing the energetics of the binary, the periastron advance, the time and frequency evolution of the gravitational wave phase for the dominant mode, and several subdominant modes. We consider different EOB models with tidal effects that have been proposed, including the model with dynamical tides of Hinderer et al. [Phys. Rev. Lett. 116, 181101 (2016), 10.1103/PhysRevLett.116.181101] and the gravitational self-force (GSF) inspired tidal EOB model of Bernuzzi et al. [Phys. Rev. Lett. 114, 161103 (2015), 10.1103/PhysRevLett.114.161103]. The EOB model with dynamical tides leads to the best representation of the systems considered here; however, the differences to the GSF-inspired model are small. A common feature is that for systems where matter effects are large, i.e., stiff equations of state or small total masses, all EOB models underestimate the tidal effects and differences to the results from numerical relativity simulations become noticeable near the merger. We analyze this regime to diagnose the shortcomings of the models in the late inspiral, where the two neutron stars are no longer isolated bodies moving in vacuum. Our work will serve to guide further advances in modeling these systems.

We consider both Hamiltonian and stochastic dynamics, the later case including electronic RC networks. We compare our theoretical predictions with the experimental data obtained by Ciliberto et al.

Lett. 116, 120404 (2016), 10.1103/PhysRevLett.116.120404] to the setting where not just the free ("incoherent") resources, but also the manipulated objects, are quantum operations rather than states. In particular, we discuss an information theoretic notion of the coherence capacity of a quantum channel and prove a single-letter formula for it in the case of unitaries. Then we move to the coherence cost of simulating a channel and prove achievability results for unitaries and general channels acting on a d -dimensional system; we show that a maximally coherent state of rank d is always sufficient as a resource if incoherent operations are allowed, and one of rank d2 for "strictly incoherent" operations. We also show lower bounds on the simulation cost of channels that allow us to conclude that there exists bound coherence in operations, i.e., maps with nonzero cost of implementing them but zero coherence capacity; this is in contrast to states, which do not exhibit bound coherence.

    In the presence of Rashba spin-orbit coupling, a magnetic field can drive a proximitized nanowire into a topological superconducting phase [R. M. Lutchyn, J. D. Sau, and S. Das Sarma, Phys. Rev. Lett. 105, 077001 (2010)., 10.1103/PhysRevLett.105.077001 and Y. Oreg, G. Refael, and F. von Oppen, Phys. Rev. Lett. 105, 177002 (2010)., 10.1103/PhysRevLett.105.177002]. We study the transport properties of such nanowires in the Coulomb blockade regime. The associated with topological superconductivity Majorana modes significantly modify transport and lead to single-electron coherent transmission through the nanowire—a nonlocal signature of topological superconductivity. In this Letter, we focus on the case of strong hybridization of the Majorana modes with normal leads. The induced by hybridization broadening of the Majorana zero-energy states competes with the charging energy, leading to a considerable modification of the Coulomb blockade in a nanowire contacted by two normal leads. We evaluate the two-terminal conductance as a function of the gate voltage, junctions transmission coefficients, and the geometric capacitance of and the induced superconducting gap in the nanowire.

    2016-12-01

    We present a derivation of the adiabatic energy relations as well as the large momentum distribution of a polarized Fermi gas near p -wave Feshbach resonances. The leading asymptotic behavior k-2 and subleading behavior k-4 of the large momentum distribution have recently been predicted by Z. Yu et al. [Phys. Rev. Lett. 115, 135304 (2015), 10.1103/PhysRevLett.115.135304] and by M. Y. He et al. [Phys. Rev. Lett. 116, 045301 (2016), 10.1103/PhysRevLett.116.045301] using two different approaches. Here, we show that the subleading asymptotic behavior (˜k-4 ) cannot fully be captured by the contact defined from the adiabatic energy relation related to the p -wave effective range, and there should be an extra term resulting from the center-of-mass motion of the pairs. The omission of this extra term is perhaps a reasonable approximation at zero temperature. However, it should be taken into account at finite temperature and should have significant importance to understand the recently measured momentum distribution in a resonant p -wave Fermi gas of ultracold 40K atoms [C. Luciuk et al., Nat. Phys. 12, 599 (2016), 10.1038/nphys3670].

    NASA Astrophysics Data System (ADS)

    Gertjerenken, Bettina; Wiles, Timothy P.; Weiss, Christoph

    2016-11-01

    We model the dynamics of attractively interacting ultracold bosonic atoms in a quasi-one-dimensional wave guide with additional harmonic trapping. Initially, we prepare the system in its ground state and then shift the zero of the harmonic trap and switch on an additional narrow scattering potential near the center of the trap. After colliding with the barrier twice, we propose to measure the number of atoms opposite the initial condition. Quantum-enhanced interferometry with quantum bright solitons allows us to predict detection of an offset of the scattering potential with considerably increased precision as compared to single-particle experiments. In a future experimental realization this might lead to measurement of weak forces caused, for example, by small horizontal gradients in the gravitational potential—with a resolution of several micrometers given essentially by the size of the solitons. Our numerical simulations are based on the rigorously proved effective potential approach developed in previous papers [Phys. Rev. Lett. 102, 010403 (2009), 10.1103/PhysRevLett.102.010403 and Phys. Rev. Lett. 103, 210402 (2009), 10.1103/PhysRevLett.103.210402]. We choose our parameters such that the prerequisite of the proof (that the solitons cannot break apart, for energetic reasons) is always fulfilled, thus exploring a parameter regime inaccessible to the mean-field description via the Gross-Pitaevskii equation due to Schrödinger-cat states occurring in the many-particle quantum dynamics.

    2017-06-01

    A renormalization group flow of Hamiltonians for two-dimensional classical partition functions is constructed using tensor networks. Similar to tensor network renormalization [G. Evenbly and G. Vidal, Phys. Rev. Lett. 115, 180405 (2015), 10.1103/PhysRevLett.115.180405; S. Yang, Z.-C. Gu, and X.-G. Wen, Phys. Rev. Lett. 118, 110504 (2017), 10.1103/PhysRevLett.118.110504], we obtain approximate fixed point tensor networks at criticality. Our formalism, however, preserves positivity of the tensors at every step and hence yields an interpretation in terms of Hamiltonian flows. We emphasize that the key difference between tensor network approaches and Kadanoff's spin blocking method can be understood in terms of a change of the local basis at every decimation step, a property which is crucial to overcome the area law of mutual information. We derive algebraic relations for fixed point tensors, calculate critical exponents, and benchmark our method on the Ising model and the six-vertex model.

    Bartsch et al. [Phys. Rev. Lett. 104, 195901 (2010), 10.1103/PhysRevLett.104.195901] reported measurements of the diffusivities of different components of the multi-component bulk metallic glass Pd43Cu27Ni10P20. The diffusion of the largest Pd and the smallest P was found to be drastically different. The Stokes-Einstein relation breaks down when considering the P constituent atom, while the relation is obeyed by the Pd atom over 14 orders of magnitude of change in Pd diffusivity. This difference in behavior of Pd and P poses a problem challenging for explanation. With the assist of a recent finding in metallic glasses that the β-relaxation and the diffusion of the smallest component are closely related processes by Yu et al. [Phys. Rev. Lett. 109, 095508 (2012), 10.1103/PhysRevLett.109.095508], we use the Coupling Model to explain the observed difference between P and Pd quantitatively. The same model also explains the correlation between property of the β-relaxation with fragility found in the family of (CexLa1-x)68Al10Cu20Co2 with 0 ≤ x ≤ 1.

    We present a numerical calculation of the total number of disordered jammed configurations Ω of N repulsive, three-dimensional spheres in a fixed volume V. To make these calculations tractable, we increase the computational efficiency of the approach of Xu et al. [Phys. Rev. Lett. 106, 245502 (2011)10.1103/PhysRevLett.106.245502] and Asenjo et al. [Phys. Rev. Lett. 112, 098002 (2014)10.1103/PhysRevLett.112.098002] and we extend the method to allow computation of the configurational entropy as a function of pressure. The approach that we use computes the configurational entropy by sampling the absolute volume of basins of attraction of the stable packings in the potential energy landscape. We find a surprisingly strong correlation between the pressure of a configuration and the volume of its basin of attraction in the potential energy landscape. This relation is well described by a power law. Our methodology to compute the number of minima in the potential energy landscape should be applicable to a wide range of other enumeration problems in statistical physics, string theory, cosmology, and machine learning that aim to find the distribution of the extrema of a scalar cost function that depends on many degrees of freedom.

    de Graaf, Joost; Filion, Laura; Marechal, Matthieu; van Roij, René; Dijkstra, Marjolein

    2012-12-01

    In this paper, we describe the way to set up the floppy-box Monte Carlo (FBMC) method [L. Filion, M. Marechal, B. van Oorschot, D. Pelt, F. Smallenburg, and M. Dijkstra, Phys. Rev. Lett. 103, 188302 (2009), 10.1103/PhysRevLett.103.188302] to predict crystal-structure candidates for colloidal particles. The algorithm is explained in detail to ensure that it can be straightforwardly implemented on the basis of this text. The handling of hard-particle interactions in the FBMC algorithm is given special attention, as (soft) short-range and semi-long-range interactions can be treated in an analogous way. We also discuss two types of algorithms for checking for overlaps between polyhedra, the method of separating axes and a triangular-tessellation based technique. These can be combined with the FBMC method to enable crystal-structure prediction for systems composed of highly shape-anisotropic particles. Moreover, we present the results for the dense crystal structures predicted using the FBMC method for 159 (non)convex faceted particles, on which the findings in [J. de Graaf, R. van Roij, and M. Dijkstra, Phys. Rev. Lett. 107, 155501 (2011), 10.1103/PhysRevLett.107.155501] were based. Finally, we comment on the process of crystal-structure prediction itself and the choices that can be made in these simulations.

  9. Current correlations in an interacting Cooper-pair beam splitter

    NASA Astrophysics Data System (ADS)

    Rech, J.; Chevallier, D.; Jonckheere, T.; Martin, T.

    2012-01-01

    We propose an approach allowing the computation of currents and their correlations in interacting multiterminal mesoscopic systems involving quantum dots coupled to normal and/or superconducting leads. The formalism relies on the expression of branching currents and noise crossed correlations in terms of one- and two-particle Green's functions for the dots electrons, which are then evaluated self-consistently within a conserving approximation. We then apply this to the Cooper-pair beam-splitter setup recently proposed [L. Hofstetter , Nature (London)NATUAS0028-083610.1038/nature08432 461, 960 (2009); Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.107.136801 107, 136801 (2011); L. G. Herrmann , Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.104.026801 104, 026801 (2010)], which we model as a double quantum dot with weak interactions, connected to a superconducting lead and two normal ones. Our method not only enables us to take into account a local repulsive interaction on the dots, but also to study its competition with the direct tunneling between dots. Our results suggest that even a weak Coulomb repulsion tends to favor positive current cross correlations in the antisymmetric regime (where the dots have opposite energies with respect to the superconducting chemical potential).

    It is shown that the cyclic evolution posed by Aharonov and Anandan [Phys. Rev.

The above results are illustrated and some specific geometric phases are given.

    The influence of parameter mismatches on multirhythmic patterns in chains of coupled Rossler circuits are explored experimentally. The parameter mismatches in coupled chaotic oscillators are found to help form a kind of multirhythmic pattern as reported in chains of biological coupled oscillators [Phys. Rev. Lett. 92 228102]. Moreover, a new type of multirhythmic pattern based on the envelope of time series is observed.

    Lee, Kegan; Kamiya, Keisuke; Nakajima, Masamichi; Miyasaka, Shigeki; Tajima, Setsuko

    2017-02-01

    A precursor of superconductivity has been searched in the in-plane optical spectra of underdoped YBa2Cu3Oy, in which the previous c-axis optical spectra showed the presence of superconducting carriers at a temperature far above Tc [Uykur et al., Lett.112.127003" xlink:type="simple">Phys. Rev. Lett. 112, 127003 (2014)][Dubroka et al., Lett.106.047006" xlink:type="simple">Phys. Rev. Lett. 106, 047006 (2011)]. By carefully subtracting the normal component from the imaginary part of conductivity σ2(ω), we found a clear in-plane response of superconducting condensate at the temperature consistent with the c-axis optical data. This confirms that the precursory superconductivity developing with decreasing doping level is an intrinsic phenomenon in the cuprates.

  20. One-dimensional repulsive Fermi gas in a tunable periodic potential

    2017-08-01

    By using unbiased continuous-space quantum Monte Carlo simulations, we investigate the ground-state properties of a one-dimensional repulsive Fermi gas subjected to a commensurate periodic optical lattice (OL) of arbitrary intensity. The equation of state and the magnetic structure factor are determined as a function of the interaction strength and of the OL intensity. In the weak OL limit, Yang's theory for the energy of a homogeneous Fermi gas [C.-N. Yang, Phys. Rev. Lett. 19, 1312 (1967), 10.1103/PhysRevLett.19.1312] is recovered. In the opposite limit (deep OL), we analyze the convergence to the Lieb-Wu theory for the Hubbard model [E. H. Lieb and F. Y. Wu, Phys. Rev. Lett. 20, 1445 (1968), 10.1103/PhysRevLett.20.1445], comparing two approaches to map the continuous space to the discrete-lattice model: The first is based on (noninteracting) Wannier functions and the second effectively takes into account strong-interaction effects within a parabolic approximation of the OL wells. We find that strong antiferromagnetic correlations emerge in deep OLs and also in very shallow OLs if the interaction strength approaches the Tonks-Girardeau limit. In deep OLs we find quantitative agreement with density-matrix renormalization-group calculations for the Hubbard model. The spatial decay of the antiferromagnetic correlations is consistent with quasi-long-range order even in shallow OLs, in agreement with previous theories for the half-filled Hubbard model.

    We extend classical-field methods [Blakie , Adv. Phys.ADPHAH0001-873210.1080/00018730802564254 57, 363 (2008)] to provide a description of atom-molecule systems. We use a model of Bose-Einstein condensation of atoms close to a Feshbach resonance, in which the tunable scattering length of the atoms is described using a system of coupled atom and molecule fields [Holland , Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.86.1915 86, 1915 (2001)]. We formulate the basic theoretical methods for a coupled atom-molecule system, including the determination of the phenomenological parameters in our system, the Thomas-Fermi description of Bose-Einstein condensate, the Bogoliubov-de Gennes equations, and the Bogoliubov excitation spectrum for a homogenous condensed system. We apply this formalism to the special case of Bragg scattering from a uniform condensate and find that for moderate and large scattering lengths, there is a dramatic difference in the shift of the peak of the Bragg spectra, compared to that based on a structureless atom model. The result is compatible with the experimental results of Papp [Phys. Rev. LettPRLTAO0031-900710.1103/PhysRevLett.101.135301 101, 135301 (2008)] for Bragg scattering from a nonuniform condensate.

    Modern string theories, which seek to produce a consistent description of physics beyond the Standard Model that also includes the gravitational interaction, appear to be most consistent if a large number of dimensions are postulated. For example the mysterious M-theory, which generalizes all consistent versions of superstring theories, require 11 dimensions. We demonstrate that investigations of quantum level energies in simple molecular systems provide a testing ground to constrain the size of compactified extra dimensions, for example those proposed in the ADD [1] and RS scenarios [2]. This is made possible by the recent progress in precision metrology with ultrastable lasers on energy levels in neutral molecular hydrogen (H_2, HD and D_2) [3] and the molecular hydrogen ions (H_2^+, HD^+ and D_2^+) [4]. Comparisons between experiment and quantum electrodynamics calculations for these molecular systems can be interpreted in terms of probing large extra dimensions, under which conditions gravity will become much stronger. Molecules are a probe of space-time geometry at typical distances where chemical bonds are effective, i.e. at length scales of an Å. [1] N. Arkani-Hamed, S. Dimopoulos and G. Dvali, Phys. Lett.

    Spin orbit coupling at interfaces can give rise to chiral magnetic textures such as homochiral domain walls and skyrmions, as well as current-induced torques that can effectively manipulate them [1-3]. This talk will describe interface-driven spin-orbit torques and Dzyaloshinskii-Moriya interactions (DMIs) in ultrathin metallic ferromagnets adjacent to nonmagnetic heavy metals. We show that the DMI depends strongly on the heavy metal, differing by a factor of ~20 between Pt and Ta [4], and describe the influence of strong DMI on domain wall dynamics and spin Hall effect switching [5]. We present high-resolution magnetic force microscopy imaging of static magnetic textures that directly reveal the role of DMI and allow its strength to be quantified. Finally, we will describe how SOTs can be enhanced through interface engineering [6] and tuned by a gate voltage [7] by directly controlling the interfacial oxygen coordination at a ferromagnet/oxide interface [8].

    2010-12-01

    Recently, we have presented spatially modulated delayed feedback as a novel mechanism, which generically generates chimera states, remarkable spatiotemporal patterns in which coherence coexists with incoherence [O. E. Omel’chenko , Phys. Rev. Lett. 100, 044105 (2008)10.1103/PhysRevLett.100.044105]. Remarkably, such chimera states serve as a natural link between completely coherent states and completely incoherent states. So far, we have studied this mechanism with a self-consistency-based numerical analysis only. In contrast, in this paper we perform a thorough dynamical description and, in particular, a stability analysis of the emerging chimera states. For this, we apply a recently developed reduction procedure [A. Pikovsky and M. Rosenblum, Phys. Rev. Lett. 101, 264103 (2008)10.1103/PhysRevLett.101.264103]. By combining analytical and numerical approaches, we systematically describe the relationship between the parameters of the delayed feedback on one hand and the properties of the chimera states on the other hand. We provide the general rules for an effective control and manipulation of the chimera states.

    Müller, Clemens; Stace, Thomas M.

    2017-01-01

    Motivated by correlated decay processes producing gain, loss, and lasing in driven semiconductor quantum dots [Phys. Rev. Lett. 113, 036801 (2014), 10.1103/PhysRevLett.113.036801; Science 347, 285 (2015), 10.1126/science.aaa2501; Phys. Rev. Lett. 114, 196802 (2015), 10.1103/PhysRevLett.114.196802], we develop a theoretical technique by using Keldysh diagrammatic perturbation theory to derive a Lindblad master equation that goes beyond the usual second-order perturbation theory. We demonstrate the method on the driven dissipative Rabi model, including terms up to fourth order in the interaction between the qubit and both the resonator and environment. This results in a large class of Lindblad dissipators and associated rates which go beyond the terms that have previously been proposed to describe similar systems. All of the additional terms contribute to the system behavior at the same order of perturbation theory. We then apply these results to analyze the phonon-assisted steady-state gain of a microwave field driving a double quantum dot in a resonator. We show that resonator gain and loss are substantially affected by dephasing-assisted dissipative processes in the quantum-dot system. These additional processes, which go beyond recently proposed polaronic theories, are in good quantitative agreement with experimental observations.

We consider it using stochastic energetics, and show that there exist systems where thermal noise helps the energy conversion.

These bounds are shown to be tight for a class of important coherent states -- maximally coherent mixed states. The trade-off relation between quantum coherence and mixedness for this measure is also discussed.

  14. Cluster preformation law for heavy and superheavy nuclei

    NASA Astrophysics Data System (ADS)

    Wei, K.; Zhang, H. F.

    2017-08-01

    The concept of cluster radioactivity has been extended to allow emitted particles with ZC>28 for superheavy nuclei by nuclear theory [Poenaru et al., Phys. Rev. Lett. 107, 062503 (2011), 10.1103/PhysRevLett.107.062503]. The preformation and emission mechanics of heavy-ion particles must be examined again before the fascinating radioactivity is observed for superheavy nuclei in laboratory. We extract the cluster preformation factor for heavy and superheavy nuclei within a preformed cluster model, in which the decay constant is the product of the preformation factor, assault frequency, and penetration probability. The calculated results show that the cluster penetration probability for superheavy nuclei is larger than that for actinide elements. The preformation factor depends on the nuclear structures of the emitted cluster and mother nucleus, and the well-known cluster preformation law S (AC) =S (α) (AC-1 )/3 [Blendowske and Walliser, Phys. Rev. Lett. 61, 1930 (1988), 10.1103/PhysRevLett.61.1930] will break down when the mass number of the emitted cluster Ac>28 , and new preformation formulas are proposed to estimate the preformation factor for heavy and superheavy nuclei.

  18. Full density-matrix numerical renormalization group calculation of impurity susceptibility and specific heat of the Anderson impurity model

    NASA Astrophysics Data System (ADS)

    Merker, L.; Weichselbaum, A.; Costi, T. A.

    2012-08-01

    Recent developments in the numerical renormalization group (NRG) allow the construction of the full density matrix (FDM) of quantum impurity models [see A. Weichselbaum and J. von Delft, Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.99.076402 99, 076402 (2007)] by using the completeness of the eliminated states introduced by F. B. Anders and A. Schiller [F. B. Anders and A. Schiller, Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.95.196801 95, 196801 (2005)]. While these developments prove particularly useful in the calculation of transient response and finite-temperature Green's functions of quantum impurity models, they may also be used to calculate thermodynamic properties. In this paper, we assess the FDM approach to thermodynamic properties by applying it to the Anderson impurity model. We compare the results for the susceptibility and specific heat to both the conventional approach within NRG and to exact Bethe ansatz results. We also point out a subtlety in the calculation of the susceptibility (in a uniform field) within the FDM approach. Finally, we show numerically that for the Anderson model, the susceptibilities in response to a local and a uniform magnetic field coincide in the wide-band limit, in accordance with the Clogston-Anderson compensation theorem.

    The interplay of spin injection in lasers and their nonlinear response leads to novel spintronic devices [1]. Such spin-lasers can enable desirable properties including threshold reduction, bandwidth enhancement, and low chirp [1-3]. These lasers can also be viewed as spin-amplifiers, since high circular polarization in the output can be achieved even with nearly spin-unpolarized injection [2,3]. In the present work, we study chirp in spin-lasers and suggest new modulation schemes to improve their performance. Supported by NSF-ECCS, U.S. ONR, AFOSR-DCT, and NSF-NEB 2020. [4pt] [1] M.

  13. Band gap engineering via doping: A predictive approach

    We employ an extension of Harrison's theory at the tight binding level of approximation to develop a predictive approach for band gap engineering involving isovalent doping of wide band gap semiconductors. Our results indicate that reasonably accurate predictions can be achieved at qualitative as well as quantitative levels. The predictive results were checked against ab initio ones obtained at the level of DFT/SGGA + U approximation. The minor disagreements between predicted and ab initio results can be attributed to the electronic processes not incorporated in Harrison's theory. These include processes such as the conduction band anticrossing [Shan et al., Phys. Rev. Lett. 82, 1221 (1999); Walukiewicz et al., Phys. Rev. Lett. 85, 1552 (2000)] and valence band anticrossing [Alberi et al., Phys. Rev. B 77, 073202 (2008); Appl. Phys. Lett. 92, 162105 (2008); Appl. Phys. Lett. 91, 051909 (2007); Phys. Rev. B 75, 045203 (2007)], as well as the multiorbital rehybridization. Another cause of disagreement between the results of our predictive approach and the ab initio ones is shown to be the result of the shift of Fermi energy within the impurity band formed at the edge of the valence band maximum due to rehybridization. The validity of our approach is demonstrated with example applications for the systems GaN1-xSbx, GaP1-xSbx, AlSb1-xPx, AlP1-xSbx, and InP1-xSbx.

    In this paper we extend the work of Elperin et al. [Phys. Rev. Lett. 80, 69 (1998)] by showing that a turbulent Dufour-type effect is also present in chemically nonreacting gaseous admixtures. This result is used to analyze the possibility of obtaining turbulent analogs of the Onsager relations, a fundamental result for molecular crossed effects in irreversible thermodynamics.
