Evidence of Strong Correlation between Instanton and QCDmonopole on SU(2) Lattice
Abstract
The correlation between instantons and QCDmonopoles is studied both in the lattice gauge theory and in the continuum theory. An analytical study in the Polyakovlike gauge, where A_{4}( x) is diagonalized, shows that the QCDmonopole trajectory penetrates the center of each instanton, and becomes complicated in the multiinstanton system. Using the SU(2) lattice with 16 ^{4}, the instanton number is measured in the singular (monopoledominating) and regular (photondominating) parts, respectively. The monopole dominance for the topological charge is found both in the maximally abelian gauge and in the Polyakov gauge.
