Abstract:
We find, in close analogy to abelian dominance in maximal abelian gauge, the phenomenon of center dominance in maximal center gauge for lattice gauge theory. Maximal center gauge is a gauge-fixing condition that preserves a residual gauge symmetry; ``center projection'' is the projection of link variables onto center elements, and ``center dominance'' is the fact that the center-projected link elements carry most of the information about the string tension of the full theory. We present numerical evidence that the thin vortices of the projected configurations are associated with ``thick'' vortices in the unprojected configurations. The evidence also suggests that the thick vortices may play a significant role in the confinement process.- 12.38.Gc
