Effective Monopole Potential for SU(2) Lattice Gluodynamics in Spatial Maximal Abelian Gauge
We investigate the dual superconductor hypothesis in finitetemperature SU(2) lattice gluodynamics in the Spatial Maximal Abelian gauge. This gauge is more physical than the ordinary Maximal Abelian gauge due to absence of non-localities in temporal direction. We show numerically that in the Spatial Maximal Abelian gauge the probability distribution of the abelian monopole field is consistent wi...
متن کاملAnatomy of Isolated Monopole in Abelian Projection of SU (2) Lattice Gauge Theory
We study the structure of the isolated static monopoles in the maximal Abelian projection of SU(2) lattice gluodynamics. Our estimation of the monopole radius is: R ≈ 0.06 fm. 1. The monopole confinement mechanism in SU(2) lattice gauge theory is confirmed by many numerical calculations (see e.g. reviews [1]). In the maximal Abelian projection monopole currents form one big cluster and several ...
متن کاملVortex Structure vs. Monopole Dominance in Abelian-Projected Gauge Theory
We find that Polyakov lines, computed in abelian-projected SU(2) lattice gauge theory in the confined phase, have finite expectation values for lines corresponding to two units of the abelian electric charge. This means that the abelian-projected lattice has at most Z2, rather than U(1), global symmetry. We also find a severe breakdown of the monopole dominance approximation, as well as positiv...
متن کاملGauge Invariant Effective Action in Abelian Chiral Gauge Theory on the Lattice
Lüscher’s recent formulation of Abelian chiral gauge theories on the lattice, in the vacuum (or perturbative) sector in infinite volume, is reinterpreted in terms of the lattice covariant regularization. The gauge invariance of the effective action and the integrability of the gauge current in anomaly-free cases become transparent. The real part of the effective action is simply one-half that o...
متن کاملThe Maximal Abelian Gauge in SU(3) Lattice Gauge Theory
We gauge fix 600 SU(3) β = 6.0 configurations on a 16 lattice to a simple form of the maximal abelian gauge. We project the SU(3) valued links to the U(1) × U(1) subgroup, and extract U(1) × U(1) and monopole string tensions. After gauge fixing to the indirect center gauge, the U(1)×U(1) links are projected to Z(3) and a vortex string tension is measured. The vortex and magnetic current densiti...
