Kinetic equation for strongly disordered systems. II. Interacting electrons

Electronic transport, in the presence of strongly disordered impurities and including the electron-electron interaction, is described via a kinetic equation of the diffusive form for the energy distribution function of quasiparticles. This equation is obtained by combining the diagrammatic treatment of the linear-response functions with a suitable identification of the distribution function itself. All known results for the number, spin, and heat correlation functions are shown to be recovered from this unified approach, with the same spirit underlying the conventional Landau theory of Fermi liquids.
