DMFT solution of the Falicov-Kimball model with an internal structure

Dynamical mean field theory is used to solve the Falicov-Kimball model in the case where the f-ions have an internal structure. The solution provides a qualitative description of the properties of Eu-based intermetallic compounds which show anomalies due to a valence-change transition.
