Gauge Invariant SO ( 3 ) - Z 2 Monopoles as Possible Source of Confinement in SU ( 2 ) Lattice Gauge Theory
نویسنده
چکیده
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 Wilson-action lattices would be far into the confining region. This suggests that Wilson-action confinement may be a strong-coupling lattice artifact; the continuum limit may not confine. 11.15.Ha, 11.30.Qc, 5.70.Fh Typeset using REVTEX

We report on further progress in our programme of understanding confinement in 3d and 4d SU(2) gauge theory in terms of Z(2) monopoles. A sufficient condition for confinement was previously translated into Z(2) monopole correlation inequalities in a related SO(3) gauge theory. We shall discuss the physical picture underlying this scenario and present some Monte Carlo evidence concerning the mon...
متن کاملEffective 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 کاملGauge invariant Z ( 2 ) vortex vacuum textures and the SU ( 2 ) gluon condensate
For SU(2) lattice gauge theory, a new SO(3) cooling procedure is proposed which removes the SU(2)/Z(2) coset fields from the lattice configurations and reveals a Z(2) vortex vacuum texture different from the P–vortex content obtained in the maximal center gauge. Cooling can be restricted in a renormalization group invariant way by a parameter controlling the remaining SO(3) action density. A ga...
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 ...

I present a unified picture of center vortices and Abelian monopoles. Both appear as local gauge ambiguities in the Laplacian Center Gauge. This gauge is constructed for a general SU (N) theory. Numerical evidence is presented, for SU (2) and SU (3), that the projected Z N theory confines with a string tension similar to the non-Abelian one. 1 Motivation and technical problem The road traveled ...
