Some properties of the model of a superconductor with pair hopping and magnetic interactions at half-filling
Konrad Kapcia
We present our preliminary studies of an effective model of a superconductor with short coherence length involving magnetic interactions. The Hamiltonian considered consists of (i)…
On the phase diagram of the zero-bandwidth extended Hubbard model with intersite magnetic interactions for strong on-site repulsion limit
Szymon Murawski, Konrad Kapcia, Grzegorz Pawłowski +1
In this report we have analyzed a simple effective model for a description of magnetically ordered insulators. The Hamiltonian considered consists of the effective on-site interact…
Interplay between charge and magnetic orderings in the zero-bandwidth limit of the extended Hubbard model for strong on-site repulsion
Konrad Kapcia, Waldemar Kłobus, Stanisław Robaszkiewicz
A simple effective model of charge ordered and (or) magnetically ordered insulators is studied. The tight binding Hamiltonian analyzed consists of (i) the effective on-site interac…
Stable and metastable phases in the atomic limit of the extended Hubbard model with intersite density-density interactions
Konrad Kapcia, Stanisław Robaszkiewicz
We have studied a simple effective model of charge ordered insulators. The tight binding Hamiltonian consists of the effective on-site interaction U and the intersite density-densi…
The effects of the next-nearest-neighbour density-density interaction in the atomic limit of the extended Hubbard model
Konrad Kapcia, Stanisław Robaszkiewicz
We have studied the extended Hubbard model in the atomic limit. The Hamiltonian analyzed consists of the effective on-site interaction U and the intersite density-density interacti…
