摘要：We investigate the QCD phase diagram based on the strong coupling expansion of the lattice QCD with one species of the staggered fermions at finite temperature (T) and chemical poten- tial (m). We analytically derive an effective potential including both chiral and deconfinement (ZNc ) dynamics with finite coupling effects in mean-field approximations. We focus on Polyakov loop properties in whole T 􀀀m plane, and study relations between the chrial and deconfinement crossovers. At a fixed large m, sequencial rapid variations of the Polyakov loop are observed with increasing T. It is natural to interprete them as the “chiral induced” and “ZNc induced” deconfinements crossovers.
