Kondo resonance behavior of heavy fermion f-electron materials (invited)

Abstract

The Kondo properties of the impurity Anderson model provide a theoretical framework for relating thermodynamic and angle integrated electron spectroscopy data in many heavy fermion materials. We describe the success and the challenges of this approach, summarize a detailed analysis of CeSi2, and give a perspective on the relation to the lattice Anderson model. © 2000 American Institute of Physics.
