Operators are constructed that introduce classical string sources and that create dynamical string loops. The operator construction in lattice gauge theory is explicitly described, and correlation ...

Non-self-dual solutions of SU(3) Yang-Mills theory and a two-dimensional Abelian Higgs model
1981-07-15

We choose a special ansatz for the gauge potentials which corresponds to Witten's ansatz; however, it involves the 5-plet of an SU(2) subalgebra instead of the 3-plet. Among the set of solutions, admitted by our ansatz, only the vacuum with vanishing field strength is self-dual. However, the action and the field equations are, ...

Non-Abelian Magnetic Monopole in a Bose-Einstein Condensate

Recently, an effective non-Abelian magnetic field with a topology of a monopole was shown to emerge from the adiabatic motion of multilevel atoms in spatially varying laser fields [J. Ruseckas et al., Phys. Rev. Lett. 95, 010404 (2005)]. We study this monopole in a Bose-Einstein condensate of degenerate dressed states and find that the ...

The nonlocal interactions among gauge variables are along the temporal direction and mimic the effect of local coupling to massless particles. In contrast to the 3D local ...

Renormalization of Gauge Fields using Hopf Algebras

We describe the Hopf algebra structure of Feynman graphs for non-Abelian gauge theories and prove compatibility of the so-called Slavnov-Taylor identities with the coproduct. When these identities are taken into account, the coproduct closes on the Green�s functions, which thus generate a Hopf subalgebra.
