Effects of nonlocal interactions on s- and d-wave superconducting correlations in the extended Hubbard model
Pavol Farkasovsky
We investigate the influence of nonlocal interactions on superconducting correlations within the extended Hubbard model. In addition to the on-site Coulomb interaction and nearest-…
The influence of nonlocal interactions on valence transitions and formation of excitonic bound states in the generalized Falicov-Kimball model
Pavol Farkasovsky
We use the density-matrix-renormalization-group (DMRG) method to study the combined effects of nonlocal interactions on valence transitions and the formation of excitonic bound sta…
Magnetic phase diagram of the Ising model with the long-range RKKY interaction
Lubomira Regeciova, Pavol Farkasovsky
The standard Metropolis algorithm and the parallel tempering method are used to examine magnetization processes in the Ising model with the long-range RKKY interaction on the Shast…
Pressure induced valence and metal-insulator transitions in the Falicov-Kimball model with nonlocal hybridization
Pavol Farkasovsky
We present a simple, but very realistic, model for a description of pressure induced valence and metal-insulator transitions in mixed valence systems. It is based on the extended F…
Magnetization plateaus and phase diagrams of the extended Ising model on the Shastry-Sutherland lattice: Effects of long-range interactions
Pavol Farkasovsky, Lubomira Regeciova
Magnetization plateaus and phase diagrams of the extended Ising model on the Shastry-Sutherland lattice with the first , second , third fourth and fif…
Effects of geometrical frustration on ferromagnetism in the Hubbard model on the Shastry-Sutherland lattice
Pavol Farkasovsky
The small-cluster exact-diagonalization calculations and the projector quantum Monte Carlo method are used to examine the competing effects of geometrical frustration and interacti…
