Thermodynamic and electromagnetic properties of the eta-pairing superconductivity in the Penson-Kolb model
Wojciech R. Czart, Konrad J. Kapcia, Roman Micnas +1
In the paper, we study the thermodynamic and electromagnetic properties of the Penson-Kolb (PK) model, i.e., the tight-binding model for fermionic particles with the pair-hopping i…

Phase separation of superconducting phases in the Penson-Kolb-Hubbard model
Konrad Jerzy Kapcia, Wojciech Robert Czart, Andrzej Ptok
In this paper we determine the phase diagrams (for as well as ) of the Penson-Kolb-Hubbard model for two dimensional square lattice within Hartree-Fock mean-field theory…

Superfluid characteristics of the attractive Hubbard model for various lattice structures
W. R. Czart, T. Kostyrko, S. Robaszkiewicz
We study the basic thermodynamic and electromagnetic properties of the superconductor described by the negative- Hubbard model (gap parameter , critical temperature , Lo…
