Effects of correlated hopping on electronic ferroelectricity in the extended Falicov-Kimball model in two dimensions
We use the Hartree-Fock (HF) approximation with the charge-density-wave (CDW) instability to study the influence of correlated hopping on the stability of electronic ferroelectricity in the extended Falicov-Kimball model (FKM) in two dimensions. It is shown that effects of the correlated hopping ter...
