Mott transition in the asymmetric Hubbard model at half-filling within dynamical mean-field theory
Ihor V. Stasyuk, Orest B. Hera
We apply the approximate analytic methods to the investigation of the band structure of the asymmetric Hubbard model where the chemical potentials and electron transfer parameters…

Densities of states of the Falicov-Kimball model off half filling in infinite dimensions
Ihor V. Stasyuk, Orest B. Hera
An approximate analytical scheme of the dynamical mean field theory (DMFT) is developed for the description of the electron (ion) lattice systems with Hubbard correlations within t…
