We investigate the influence of disorder (impurities) on the electronic (transport) properties of heavy fermion systems, which are described by the periodic Anderson model (PAM). In this paper we consider disorder within the conduction band. The PAM

The influence of substitutional disorder on the transport properties of heavy-fermion systems is investigated. We extend the dynamical mean-field theory treatment of the periodic Anderson model (PAM) to a coherent-potential approximation for disorder

Heavy fermion systems (HFS) are described by the periodic Anderson model (PAM), which is studied within the dynamical mean-field theory (DMFT), mapping the PAM on an effective single-impurity Anderson model (SIAM) to be determined selfconsistently, w

The temperature dependence of the thermoelectric power (TEP) of metallic systems with cerium and ytterbium ions exhibits characteristic features which we explain by the Coqblin-Schrieffer model (CSM). We specify a given system by the degeneracy and s

We investigate the (electronic) transport properties and the characteristic low-temperature scales of heavy-fermion systems (HFS), which are described within the periodic Anderson model (PAM). The PAM is mapped onto an effective single impurity Ander
