Gauge Invariant SO ( 3 ) - Z 2 Monopoles as Possible Source of Confinement in SU ( 2 ) Lattice Gauge Theory

A gauge invariant procedure for extracting combined SO(3)-Z2 monopoles in positive-plaquette SU(2) lattice gauge theory is shown. When these monopoles are eliminated through a constraint, the theory deconfines for all β on 12 and 20 lattices even in the strong coupling limit, despite a rather strong average plaquette of around 0.64. This corresponds to an effective Wilson β of 2.45, at which Wi...

Monopoles and instantons in SU(2) lattice gauge theory

We investigate the monopole-instanton correlation in SU(2) lattice gauge theory using a renormalisation group inspired smoothing technique. We look at the properties of monopole clusters and their correlation with instantons. Since the action of the smoothed configurations is dominated by instantons we compare the smoothed Monte Carlo lattices to artificially reconstructed configurations with t...

Monopoles and deconfinement transition in SU(2) lattice gauge theory

We investigate SU(2) lattice gauge theory in four dimensions in the maximally abelian projection. Studying the effects on different lattice sizes we show that the deconfinement transition of the fields and the percolation transition of the monopole currents in the three space dimensions are precisely related. To arrive properly at this result the uses of a mathematically sound characterization ...

Z 2 Monopoles , Vortices , and The Deconfinement Transition in Mixed Action SU ( 2 ) Gauge Theory

Adding separate chemical potentials λ and γ for Z2-monopoles and vortices respectively in the Villain form of the mixed fundamental-adjoint action for the SU(2) lattice gauge theory, we investigate their role in the interplay between the deconfinement and bulk phase transitions using Monte Carlo techniques. Setting λ to be nonzero, we find that the line of deconfinement transitions is shifted i...

Gauge Invariant Monopoles in Lattice Su(2) Gluodynamics

We consider lattice implementation of the recently proposed gauge invariant definition of the monopole charge. Because of the lattice discretization the algorithm gives rise to specific lattice artifacts and an effective Ising model. The Ising-model problem might in principle be solved and we discuss the role of the Maximal Abelian gauge in this respect. The lattice artifacts are much more diff...
