Understanding QCD phase diagram and phase transitions from the interplay between lattice techniques and low-energy effective models

This project combines lattice calculations and effective field theory techniques to investigate the behavior of strongly interacting matter. We will give attention to the axial and chiral symmetries breaking and its restoration in Polyakov-loop extended Nambu-Jona-Lasinio (PNJL) type models. Also using a PNJL type model, we will also investigate the QCD equation of state and phase diagram. We also plan to continue our investigations towards a more realistic non local low-energy effective theory for QCD. We are currently investigating the properties of a non local NJL type model, obtained by the use of (quenched) lattice calculations for the Landau gauge gluon propagator at finite temperature. Furthermore, we also aim to study the influence of dynamical fermions on the gluon propagator at non zero temperature, and how our non local model changes.
