Coupling of pion condensate, chiral condensate and Polyakov loop in an extended NJL model
The Nambu Jona-Lasinio model with a Polyakov loop is extended to finite isospin chemical potential case, which is characterized by simultaneous coupling of pion condensate, chiral condensate and Polyakov loop. The pion condensate, chiral condensate and the Polyakov loop as functions of temperature and isospin chemical potential are investigated by minimizing the thermodynamic potential of the s...
متن کاملPolyakov loop, Quasiparticles and QCD Phase Diagram
QCD thermodynamics has been the subject of intense investigations in recent years. In order to interpret corresponding lattice QCD results the Polyakov-loop extended Nambu Jona-Lasinio (PNJL) model is a promising field theoretical quasiparticle model [1, 2, 3, 4] combining the two principal non-perturbative features of lowenergy QCD: confinement and spontaneous chiral symmetry breaking. In the ...
متن کاملInhomogeneous Polyakov loop induced by inhomogeneous chiral condensates
We study the spatial inhomogeneity of the Polyakov loop induced by inhomogeneous chiral condensates. We formulate an effective model of gluons on the background fields of chiral condensates, and perform its lattice simulation. On the background of inhomogeneous chiral condensates, the Polyakov loop exhibits an in-phase spatial oscillation with the chiral condensates. We also analyze the heavy q...

متن کاملChiral symmetry at finite T , the phase of the Polyakov loop and the spectrum of the Dirac operator
Chiral symmetry at finite T , the phase of the Polyakov loop and the spectrum of the Dirac operator. Abstract A recent Monte Carlo study of quenched QCD showed that the chiral conden-sate is non-vanishing above T c in the phase where the average of the Polyakov loop P is complex. We show how this is related to the dependence of the spectrum of the Dirac operator on the boundary conditions in Eu...
