摘要The phase diagram at finite temperature and density is investigated in the framework of the Polyakov linear sigma model (PLSM) with three light quark flavors in the mean field approximation. It is found that in the PLSM, the three phase transitions, i.e. the chiral restoration of u, d quarks, the chiral restoration of s quark and the deconfinement phase transition, are independent. There exists a two-flavor quarkyonic phase at low-density and a three-flavor quarkyonic phase at high density. The critical end point (CEP) which separates the crossover from the first-order line in the PLSM model is located at (T-E, mu(E)) = (188 MeV, 139.5 MeV). In the transition region, the thermodynamic properties and the bulk viscosity over entropy density ratio zeta/s are also discussed in the PLSM.
