It is to be fully shown in this dissertation that a more fruitful, theoretical framework emerges when one dynamical ansatz supplements the previous theory; the ansatz is called level realization. With the aid of asymptotic ...

1984-01-01

After twenty years of intense scrutiny CP violation is apparently still well described, if not explained, by the superweak hypothesis, in which absolute values ..delta..S = 2 (T-violating) transitions between the K/sup 0/, anti K/sup 0/ states induce CP violating impurities in the K/sub L//sup 0/, K/sub S//sup 0/ states. CP-violating effects observed in ...

Theoretical study on local defect structure of (FeO4)(5-) clusters in YGG and LGG crystals.
2009-02-21

The optical spectrum and the local defect structure of tetrahedral (FeO4)(5-) clusters are investigated in yttrium gallium garnet (YGG) and lutetium gallium garnet (LGG) crystals by means of the 252x252 complete energy matrices for d(5) configuration ions in tetragonal ligand field. The results show that the local defect structures around tetrahedral Fe3+ centers display an expansion effect. ...

Entanglement, quantum phase transition, and scaling in the XXZ chain
2003-10-01

Motivated by recent development in quantum entanglement, we study relations among concurrence C, SU{sub q}(2) algebra, quantum phase transition and correlation length at the zero temperature for the XXZ chain. We find that at the SU(2) point, the ground state possesses the maximum concurrence. When the anisotropic parameter {delta} is deformed, however, its value decreases. ...

2005-02-21

The synthesis of dinuclear derivatives of trovacene (eta7-C7H7)V(eta5-C5H5) (1.) is reported, in which ethynyl (6..), butadiynyl (7..), and 1,4-di(ethynyl)phenyl (8..) groups serve as spacers between paramagnetic (S = 1/2) [5]trovacenyl units. The mononuclear precursors [5]trovacenylcarbaldehyde (2.) and [5]trovacenylacetylene (4.) are also described. Structural characterization by X-ray ...

Ferrocene-cyclam: a redox-active macrocycle for the complexation of transition metal ions and a study on the influence of the relative permittivity on the coulombic interaction between metal cations.
2001-07-01

The reaction of 1,1'-ferrocene-bis(methylenepyridinium) salt with 1,4,8,11-tetraazacyclotetradecane-5,12-dione, followed by LiAlH4 reduction results in the formation of FcCyclam. Metal complexes of FcCyclam with M2+ = Co2+, Ni2+, Cu2+, and Zn2+ were synthesized from FcCyclam and the respective metal triflates. The complexation of Cu2+ and FcCyclam in CH3CN is preceeded by a rapid electron ...

The concept of the absolute half-cell potential is discussed from a simple thermodynamic point of view and defined as -..delta..G/ne for the half-cell reaction, treating the electron like other individual chemical species. With the standard reference state of the electron taken as the free electron at rest at infinity, the absolute ...

Tidal-shock relaxation: A reexamination of tidal shocks in stellar systems
1995-01-01

The phenomenon of 'tidal-shock relaxation' is defined and quantitatively estimated. We show that the second-order term mean value of ((delta E)2) which has usually been neglected in the treatment of tidal shocks, is typically far more important than the first-order term mean value of (delta E). The latter has been found by Aguilar, Ostriker & Hut ...

A method is presented to measure the absolute value of the London penetration depth, {lambda}(T=0), from the frequency shift of a resonator. The technique involves coating a high-T{sub c} superconductor with film of low-T{sub c} material of known thickness and penetration depth.

Elastic and vibrationally inelastic scattering of low-energy electrons from propane

In a crossed-beam experiment, differential cross sections (DCS) for elastic and vibrationally inelastic scattering of electrons from propane have been measured in the energy range E = 0.5-10 eV. Absolute values are obtained by using e--He scattering as a reference system. For elastic scattering, the measured DCS are analysed by phase-shift analysis and modified effective-range ...

We prove on-diagonal bounds for the heat kernel of the Dirichlet Laplacian $-\\Delta^D_\\Omega$ in locally twisted three-dimensional tubes $\\Omega$. In particular, we show that for any fixed $x$ the heat kernel decays for large times as $\\mathrm{e}^{-E_1t}\\, t^{-3/2}$, where $E_1$ is the fundamental eigenvalue of the Dirichlet ...

Effects of a Superheavy, Weak-Isoscalar Quark on Flavor-Changing Neutral Current Processes, Especially Charge-Parity Violation in Neutral Z Decay.
1987-01-01

A superheavy, weak-isoscalar, Q = -1/3 quark is added to the Standard Model, inducing tree-level flavor-changing neutral currents (TLFCNCs) involving only the Q = -1/3 quarks. Although constrained by current low-energy experimental data to be extremely weak, it is nonetheless found that the tree-level s rightleftharpoons d mixing strength could still be large enough to increase the ...
