| Abstract: | A set of coupled equations for a quantum statistical system that determine self-consis-tently the order parameter, the energy spectrum, the dissipation and the distribution for both fermion field and collective excitation is suggested with a loop expansion formalism. They are applicable to non-equilibrium as well as equilibrium systems. |
