Extended Falicov-Kimball model at weak onsite and intersite Coulomb interactions
We analyze in detail a behavior of the order parameter in the half-filled extended Falicov-Kimball model for small Coulomb interactions (both onsite U and intersite V). The parameter is defined as the difference of localized electron concentrations in both sublattices of the Bethe lattice (in the li...
