We investigate the formation of quark and diquark condensates in two different situations. First, we study the phenomenon of chiral and color symmetry breaking and their restoration for a uniformly accelerated observer due to the thermalization Hawking-Unruh effect. The gap equations for quark and diquark condensates with finite chemical potential are constructed. The critical value of acceleration is also obtained. Second, we consider the phase transitions in dense matter with quark and diquark condensates in the static Einstein universe at finite temperature and chemical potential. The nonperturbative expression for the thermodynamic potential is obtained. The phase portraits of the system are constructed.
