Research Abstract

QCD in extreme conditions is expected to provide information at the early universe and the center of the neutron stars based on the fundamental principle. High energy heavy ion collision experiments also are the target. We studied the effects of a topological singularity of the gluon field on the confinement numerically, and improved several algorithms which circumvent the sign problem in the finite density Monte Carlo simulations.
