Abstract
One of the most difficult quantities to calculate for the non-degenerate Anderson and Kondo models has been the resistivity in the cross-over region between the low-temperature Fermi liquid and the high-temperature perturbative regimes. Here we show that this quantity can be calculated via an extension of the numerical renormalization group method. We present results deduced from the spectral density as a function of temperature over the full temperature range. The approach can be used to explore the full parameter space of the Anderson model, including additional interactions such as conduction-electron screening.
