INSTANTONS AND MONOPOLES ARE LOCALLY CORRELATED WITH THE CHIRAL CONDENSATE

We perform a mutual analysis of the topological and chiral vacuum stru cture of four-dimensional QCD on the lattice at finite temperature. Co ncerning the topological sector, correlation functions between the dis tributions of color magnetic monopoles in the maximum Abelian gauge an d the densities of topological charge are computed. An enhanced probab ility for monopoles inside the core of an instanton is found on the ga uge field average and in specific configurations. In the chiral sector , clear evidence is found that monopole loops and instantons are local ly correlated with the quark condensate.
