A Monte Carlo study of the Falicov–Kimball model in the perturbative regime
Finite-temperature properties of the Falicov–Kimball model on the square lattice have been studied in
 the perturbative regime, i.e. for t/U << 1, where t is the hopping constant and U denotes the Coulomb interaction
 strength. In our study, we have determined the phase...

| description | Finite-temperature properties of the Falicov–Kimball model on the square lattice have been studied in
the perturbative regime, i.e. for t/U << 1, where t is the hopping constant and U denotes the Coulomb interaction
strength. In our study, we have determined the phase diagram of the model in the second-order of the
perturbation theory, where the antiferromagnetic Ising model in the magnetic field emerges. In the fourth-order,
where our model constitutes the Ising model with more complicated frustrated antiferromagnetic interactions,
the sketch of the phase diagram was established. The Monte Carlo method was employed and the behavior
of Binder cumulants based on the order parameters was analyzed to determine the type of ordering
and phase boundaries in the diagram.
