We investigate the influence of the asymmetric quark matter (ρu ρd ρs) on the mass of the quasiparticles and the phase diagram of the chiral quark model parametrized at the one-loop level of the renormalized theory, using the optimized perturbation theory for the resummation of the perturbative series. The effect of various chemical potentials introduced in the grand canonical ensemble is investigated with the method of relativistic many-body theory. The temperature dependence of the topological susceptibility is estimated with the help of the Witten-Veneziano mass formula.
