Dynamical breaking and restoration of chiral and color symmetries in the static Einstein universe

We study the behavior of quark and diquark condensates in the framework of the extended Nambu-Jona-Lasinio model under the influence of a gravitational field in the static D-dimensional Einstein universe at finite temperature and quark density. The thermodynamic potential and the gap equations for the model are obtained. Quark and diquark condensates as functions of the chemical potential and temperature at different values of the curvature have been studied. Phase portraits of the system have been constructed.
