Quark matter with a magnified baryon density dependents Polyakov loop

This study investigates the behavior of the Polyakov loop trace at higher baryon densities in quark matter. The results show that the trace values of Polyakov loop increases monotonically with temperature up to approximately 180 MeV, beyond which it saturates and becomes nearly independent of baryon density. The conjugate trace of the Polyakov loop exhibits distinct behavior across the entire temperature range, with higher values observed at larger baryon densities. To determine the pseudo-critical temperature, the temperature derivative of the Polyakov loop trace was evaluated. The position of this differential peak identifies the pseudo-critical temperature and characterizes the crossover transition associated with chiral symmetry restoration in the quark-gluon plasma (QGP).
