The influence of correlated hopping on valence and metal-insulator transitions in the Falicov-Kimball model
P. Farkasovsky
The extrapolation of small-cluster exact-diagonalization calculations is used to examine the influence of correlated hopping on valence and metal-insulator transitions in the one-d…

Phase separation and metal-insulator transitions in the spin-one-half Falicov-Kimball model
P. Farkasovsky
The ground-state phase diagram of the spin-one-half Falicov-Kimball model (FKM) is studied in the one dimension using small-cluster exact-diagonalization calculations. The resultan…

Does the Falicov-Kimball model allow for a ferroelectric ground state with a spontaneous polarization?
P. Farkasovsky
The extrapolation of small-cluster exact-diagonalization calculations is used to examine the possibility of electronic ferroelectricity in the one dimensional spinless and spin-one…
