“…is the total isospin density. As shown in the previous study [66][67][68][69][70][71][72][73][74][75][76], the phase transition features of asymmetric matter are isospin dependent. Once the species of heavy ions are chosen in HIC experiments, the asymmetry parameter will be determined.…”

“…This approach is widely used in the description of the phase transition in neutron star with a quark core or kaon condensate [56][57][58][59][60][61][62][63][64][65]. It is also generalized to explore the phase transformation from nuclear to quark matter at finite density and temperature in HICs [66][67][68][69][70][71][72][73][74][75][76].…”

“…In our previous study [73][74][75][76], attention was focused on the isospin asymmetric matter, and some observable effects on isospin-relevant meson yield ratios were proposed. As a further study along this line, in this study we take a chemical potential dependent Polyakov loop potential in the PNJL model to construct the two-phase model and explore the full QCD phase diagram.…”

We construct a hadron-quark two-phase model based on the Walecka-quantum hadrodynamics and the improved Polyakov-Nambu-Jona-Lasinio model with an explicit chemical potential dependence of Polyakov-loop potential (µPNJL model). With respect to the original PNJL model, the confineddeconfined phase transition is largely affected at low temperature and large chemical potential. Using the two-phase model, we investigate the equilibrium transition between hadronic and quark matter at finite chemical potentials and temperatures. The numerical results show that the transition boundaries from nuclear to quark matter move towards smaller chemical potential (lower density) when the µ-dependent Polyakov loop potential is taken. In particular, for charge asymmetric matter, we compute the local asymmetry of u, d quarks in the hadron-quark coexisting phase, and analyse the isospin-relevant observables possibly measurable in heavy-ion collision (HIC) experiments. In general new HIC data on the location and properties of the mixed phase would bring relevant information on the expected chemical potential dependence of the Polyakov Loop contribution.

“…The chiral properties are taken care of by the NJL part, while the confinement properties and the gluonic contributions are effectively incorporated through the Polyakov loop potential. Various studies have been carried out using PNJL model with 2 and 2 þ 1 flavors [12,[21][22][23][24][25][26][27][28][29][30]. For our study we shall use the 2 þ 1 flavor model having up to six quark interactions.…”

Thermodynamic properties of strongly interacting matter are investigated using the Polyakov loop enhanced Nambu-Jona-Lasinio model along with some modifications to include the hadrons. Various observables are shown to have a close agreement with the numerical data of QCD on lattice. The advantage of the present scheme over a similar study using a switching function is that here no extra parameters are to be fitted. As a result the present scheme can be easily extended for finite chemical potentials.
