Aharonov-Bohm effect, center monopoles and center vortices in SU(2) lattice gluodynamics

SU(2) gluodynamics is investigated numerically and analytically in the (Ind irect) Maximal Center gauge at finite temperature. The center vortices are shown to be condensed in the confinement phase and dilute in the deconfinem ent phase. A new physical object, center monopole, is constructed. We show that the center monopole condensate is the order parameter of deconfinement phase transition. The linking of the vortex worldsheets and quark trajecto ries is identified with the Aharonov-Bohm interaction in an effective Abeli an Higgs theory. We conclude that the confinement in the Maximal Center gau ge can be explained by a new mechanism called "the real superconductor mech anism".
