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…

Multiple phase transitions in Pauli limited iron-based superconductors
Andrzej Ptok
Specific heat measurements have been successfully used to probe unconventional superconducting phases in one-band heavy-fermion and organic superconductors. We extend the method to…

Probe-type of superconductivity by impurity in materials with short coherence length: the s-wave and -wave phases study
Andrzej Ptok, Konrad Jerzy Kapcia
The effects of a single non-magnetic impurity on superconducting states in the Penson-Kolb-Hubbard model have been analyzed. The investigations have been performed within two steps…
