Color ordering of quark matter

The Landau Fermi-liquid theory is generalized for a system of fermions with a "color degree of freedom" (quark plasma). It is shown that the phase tra nsition to color ordering state may occur depending on the change in thermo dynamic parameters similar to a magnetic phase transition taking place for fermions with spin. The problem of thermodynamic stability of color and mag netic ordered Fermi-liquids is considered. It is shown that the stable colo r-ordered state of the plasma light quarks (u, d quarks) can be at the dens ity n similar to 10(37) cm(-3) and the temperature T similar to 100MeV.
