Quark matter within Polyakov chiral SU(3) quark mean field model at finite temperature

Thermodynamical properties and phase diagram of asymmetric strange quark matter using the Polyakov chiral SU(3) quark mean field (PCQMF) model at finite temperature and chemical potential have been investigated. Within the PCQMF model, the properties of quark matter are calculated through the scalar fields sigma, zeta, delta and chi, the vector fields omega, rho and phi and the Polyakov loop fields Phi and Phi . The isospin splitting of constituent quark masses is observed at large isospin asymmetry. The effect of temperature and strangeness fraction on energy per baryon and equation of state is found to be appreciable in quark matter. The effect of the Polyakov loop dynamics on several thermodynamical bulk quantities such as energy density, entropy density and trace anomaly is presented. Furthermore, within the model under mean field approximation, we explore the phase structure in T-mu plane and analyzed the impact of varying the strength of vector coupling and isospin chemical potential on nature of phase transition.

Automated summary

The thermodynamical properties and phase diagram of asymmetric strange quark matter were investigated using the Polyakov chiral SU(3) quark mean field model, with a focus on isospin splitting, the effects of temperature and strangeness fraction on energy and equation of state, and the impact of Polyakov loop dynamics on bulk quantities. Phase structure in the T-mu plane and the influence of varying vector coupling strength and isospin chemical potential on phase transition nature were explored within the mean field approximation model.
