Query: Effects of entanglement and instanton suppression at finite temperature
  in a SU(2) EPNJL model with anomaly   We investigate the phase transitions characterized by deconfinement and
restoration of chiral and axial symmetries,at finite temperature, in the
framework of QCD inspired models. We compare the results obtained in the SU(2)
Polyakov-Nambu-Jona-Lasinio model with anomaly and in its extended version, the
Entangled Polyakov-Nambu-Jona-Lasinio model. In the last version, four-quark
vertices with entanglement between the chiral condensate and the Polyakov loop
are considered. The thermodynamics of the phase transitions, the meson
spectrum, and in particular the convergence of axial and chiral partners, will
be analyzed, as well as the topological susceptibility. We find that an
explicit temperature dependence of the coupling vertices is necessary in both
models in order to have effective restoration of the U$_A$(1) symmetry.
