Sažetak
We develop the 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 YbInCu$_4$ and EuNi$_2$(Si$_{; ; ; ; 1-x}; ; ; ; $Ge$_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.
