Transport properties of the Anderson model at finite U

Kondo behaviour of electrical resistivities, Lorenz number ratios and thermopowers is examined for the N-fold degenerate impurity-Anderson model at finite U and temperature as function of these parameters and the position of the f-level, using an extension of the non-crossing approximation. The negative thermopower changes sign with growing U, the Hall coefficients show negative minima while spin correlation functions agree with Monte Carlo results. (orig.)
