Transport properties of a multicomponent Fermi liquid

Abstract
Starting from the Landau kinetic equation, we derive exact expressions for transport coefficients of a multicomponent Fermi liquid. We consider arbitrary ratios of Fermi momenta and effective masses, and completely general scattering rates. As specific examples we evaluate the thermal conductivity, shear viscosity, and diffusion coefficients for the multicomponent system, and give further details for the two-component case.
