Theory of valence transitions in ytterbium-based compounds

Strongly Correlated Electrons 2007-05-23 v1

Abstract

The anomalous behavior of YbInCu4 and similar compounds is modeled by the exact solution of the spin one-half Falicov-Kimball model in infinite dimensions. The valence-fluctuating transition is related to a metal-insulator transition caused by the Falicov-Kimball interaction, and triggered by the change in the f-occupancy.
