Quark Matter within Polyakov Chiral SU(3) Quark Mean Field Model at Finite Temperature

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

\bar{\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.
