Instantons and Monopoles in the Nonperturbative QCD

Abstract

Based on the dual-superconductor picture, we study the confinement physics in QCD in terms of the topological objects as monopoles in the maximally abelian (MA) gauge using the SU(2) lattice QCD. In the MA gauge, the off-diagonal gluon component is forced to be small, and hence microscopic abelian dominance on the link variable is observed in the lattice… (More)
