摘要：
Quark propagator and Polyakov loop are measured in a singular(monopole) and a regular(photon) part of an abelian sector defined through maximal abelian projection from SU(2) gauge field at finite temperature. Both the abelian field and the singular part clearly show the feature of chiral breaking/restoration at low/high beta's in terms of quark condensates (quench staggered quark) and confinement/deconfinement behavior in the Polyakov loop. On the other hand, in the regular part, no indication of chiral breaking is seen and color is deconfined even in a region below beta(c)(SU(2)).
