A study of the QCD phase diagram based on microscopic models
Abstract:
In this talk we review some applications of two microscopic low-energy models, ladder-QCD and Nambu-Jona-Lasinio, to study the QCD phase diagram. In the first part of the talk we focus our attention to the physics of low temperatures and high quark densities, and we consider the phenomenon of pion and kaon condensation, which could be relevant for the physics of compact stars. These effects, proposed starting from the '70s in the framework of nuclear physics, have been the subject of many studies in recent years by using effective models of QCD.
In the second part of the talk, we discuss several aspects concerning the behaviour of the chiral critical line; this analysis was mainly motivated for establishing a comparison with lattice data.
