摘要：
A system of quasi-particles with scattering on arbitrary static potential is considered by means of non-equilibrium Green function method in Kadanoff-Baym formulation. The problem of kinetic coefficients evaluation can be solved with Kadanoff-Baym quantum kinetic equations for the system in the presence of an external field. A variational method of solution for linearized over-external field quantum kinetic equations is proposed.
