Valence Fluctuations in the Extended Periodic Anderson Model at Finite Temperatures

Abstract

We study valence fluctuation at finite temperatures in the periodic Anderson model with the Coulomb interaction between $f$ and conduction electons, combining dynamical mean-field theory with the non-crossing approximation. It is found that a large Coulomb repulsion induces a first-order valence transition. The finite temperature phase diagram is determined.
