Thermodynamics of the Polyakov-Dyson-Schwinger model

We review thermodynamic properties (pressure, energy and entropy density ...) of quark matter at finite temperature within the framework of the Polyakov-Dyson-Schwinger model. For the investigation we use a covariant, nonlocal separable model which allows to solve straightforwardly the Dyson-Schwinger equations for quark and meson propagators as well as to evaluate the partition function. Different scenarios are discussed by comparing different ansaetze for the dressed gluon interaction, including also the limit of the PNJL model, widely explored recently in discussing the low-energy QCD phase diagram.
