Scaling properties of transport coefficients for the finite U Anderson model

We discuss here transport coefficients which are due to degenerate Anderson impurities with a finite onsite Coulomb interaction U. Using our recently calculated expression for the Abrikosov-Suhl resonance where the Kondo singlet energy shift T₀(U) enters explicitly we show that the resistivity ratio ρ(T)/ρ(T=0) and the thermopower S scale with the reduced temperature T/T₀(U) as expected. By comparison with the full numerical NCA results for infinite U we estimate that the above calculations are quantitatively reliable up to T/T₀(U)≃0.2. For this range simple analytical expressions are given as function of the reduced temperature.
