Thermoelectric power (TEP) of the Kondo insulators is investigated theoretically within the framework of the dynamical mean field theory. It is found that the temperature dependence of the Seebeck coefficient changes from the ordinary behavior S ( T

Effects of electron correlation in FeSi are studied in terms of the two-band Hubbard model with the density of states obtained from the band calculation. Using the self-consistent second-order perturbation theory combined with the local approximation

Seebeck coefficient S of the Kondo insulators is investigated theoretically within the framework of the dynamical mean field theory. It is found that the temperature dependence changes from the ordinary behavior S ( T ) ∝ T -1 in semiconductors to

We study the two-band Hubbard model introduced by Fu and Doniach as a model for FeSi which is suggested to be a Kondo insulator. Using the self-consistent second-order perturbation theory combined with the local approximation which becomes exact in t

The two-band Hubbard model with the density of states obtained from the band calculation for FeSi is investigated. The temperature dependence of the density of states and the optical conductivity are calculated with self-consistent second-order pertu
