Correlated hopping in the 1D Falicov-Kimball model
Both canonical and grand canonical phase diagrams of the one-dimensional Falicov-Kimball model (FKM) with correlated hopping are presented for several values of the model parameters. Using the method of restricted phase diagrams the system has been studied in the thermodynamic limit. As compare to the conventional FKM, the diagrams exhibit a loss of the hole-particle symmetry.
