dc.descriptionWe 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 is reminiscent of the Mooij correlations observed in many disordered metals.
