Phase diagram of neutron star quark matter in nonlocal chiral models

We study the phase diagram of two-flavor quark matter under neutron star constraints for the case of nonlocal, ovariant quark models within the mean field approximation. At intermediate densities, it is seen that various low-temperature quark matter phases can occur. On the other hand, critical temperatures at zero chemical potential are found to be in better agreement with lattice QCD results than the prediction of the standard local NJL model.
