Monopole Order Parameter in Su (2) Lattice Gauge Theory *
We present the results of the numerical calculation of the probability distribution of the value of the monopole creation operator in SU (2) lattice gluodynamics. We work in the maximal abelian projection. It occurs that at the low temperature, below the deconfinement phase transition the maximum of the distribution is shifted from zero, which means that the effective constraint potential is of...
متن کاملCompact U ( 1 ) Lattice Gauge – Higgs Theory with Monopole Suppression ∗
We investigate a model of a U(1)–Higgs theory on the lattice with compact gauge fields but completely suppressed (elementary) monopoles. We study the model at two values of the quartic Higgs self–coupling, a strong coupling, λ = 3.0, and a weak coupling, λ = 0.01. We map out the phase diagrams and find that the monopole suppression eliminated the confined phase of the standard lattice model at ...
متن کاملMonopole Anti - monopole excitation in MAG projected SU ( 2 ) lattice gauge theory
Maximal Abelian gauge fixing and subsequent Abelian projection of SU(2) lattice gauge theory defines closed trajectories of magnetic monopoles. These trajectories can be interpreted in terms of an effective scalar field theory of the MAG monopoles using the worldline representation of the functional determinants. Employing the monopole worldlines detected in the numerical simulation, we show th...
متن کاملOn projection ( in ) dependence of monopole condensate in lattice SU ( 2 ) gauge theory
We study the temperature dependence of the monopole condensate in different Abelian projections of the SU (2) lattice gauge theory. Using the Fröhlich-Marchetti monopole creation operator we show numerically that the monopole condensate depends on the choice of the Abelian projection. Contrary to the claims in the current literature we observe that in the Abelian Polyakov gauge and in the field...
متن کاملProperties of P - vortex and monopole clusters in lattice SU ( 2 ) gauge theory
We study the action and geometry of P-vortices, discriminating between the percolating and finite clusters. We also discuss the interrelation of the monopoles and P-vortices. To define P-vortices we use both the direct maximal center projection and indirect maximal center projection. We find, in particular, that the action density of the P-vortices in short clusters is substantially higher than...
