Pattern formation in the Falicov–Kimball model

Maciej M. Maśka, Katarzyna Czajka

Abstract It is known that in the ground state of half‐filled Falicov–Kimball model immobile particles form a checkerboard pattern. On the other hand, there is a wide range of model parameters, for which this model is expected to exhibit a phase separation. Using Monte Carlo simulations we demonstrate how the system reaches these states, as the temperature is lowered. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Thermodynamics of the two-dimensional Falicov-Kimball model: a Monte Carlo study

Maciej M. Maśka, Katarzyna Czajka

The two-dimensional Falicov-Kimball (FK) model is analyzed using Monte Carlo method. In the case of concentrations of both itinerant and localized particles equal to 0.5 we determine temperature dependence of specific heat, charge density wave susceptibility and density-density correlation function. In the weak interaction regime we find a first order transition to the ordered state and anomalous temperature dependence of the correlation function. We construct the phase diagram of half-filled FK model. Also, the role of next-nearest-neighbor hopping on the phase diagram is analyzed. Lastly, we discuss the density of states and the spectral functions for the mobile particles in weak and strong interaction regime.
