Effective monopole potential for SU(2) lattice gluodynamics in the spatialmaximal Abelian gauge

We investigate the dual superconductor hypothesis in finite-temperature 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 no nlocalities in the temporal direction. We show numerically that in the spat ial maximal Abelian gauge the probability distribution of the Abelian monop ole field is consistent with the dual superconductor mechanism of confineme nt: the Abelian condensate vanishes in the deconfinement phase and is nonze ro in the confinement phase.
