Resonant enhancement of thermoelectric properties by correlated hopping for the Falicov-Kimball model on Bethe lattice
An influence of correlated hopping of the charge and heat transport in the strongly correlated material described by the Falicov-Kimball model is considered. An exact solutions for the density of states and transport coefficients are derived within the dynamical mean field theory for the Bethe lattice. It is obtained that “quasiparticle” scattering time in Boltzmann relations is governed by the two particle resonant contributions leading to large increasing of the charge and heat conductivities and thermoelectric power. Besides, an additional narrow band of localized states placed between the lower and upper Hubbard bands is observed with minor contribution in thermoelectric properties.
