Localization effects and inelastic scattering in disordered heavy electrons

We study ground-state and finite-temperature properties of disordered heavy fermion metals by using a generalization of dynamical mean-field theory which incorporates Anderson localization effects. The emergence of a non-Fermi-liquid metallic behavior even at moderate disorder is shown to be a universal phenomenon resulting from local density of states fluctuations. This behavior is found to have a character of an electronic Griffiths phase, and can be thought of as a precursor of Anderson localization in a strongly correlated host. The temperature dependence of the conducting properties of the system reveal a non-trivial interplay between disorder and inelastic processes, which are reminiscent of the Mooij correlations observed in many disordered metals.
