Abstract

We develop a formalism to solve the multicomponent Falicov-Kimball model with dynamical mean-field theory, allowing for all possible crystal-field couplings (including spin-orbit coupling). We apply these techniques to solve models of the intermediate-valence transition [as seen in YbInCu₄ and EuNi₂(Si_1-xGe_x)₂] in the simple limit of no crystal field or spin-orbit coupling. We show results for the uniform spin susceptibility, the average localized electron concentration, and transport properties. We also investigate the metamagnetic transition.
