Superconductivity, Charge Orderings and Phase Separations in Systems with Local Electron Pairing
S. Robaszkiewicz, G. Pawlowski
We study two effective models developed for description of superconductors with short-coherence length: (i) the extended Hubbard model with on-site attraction and intersite repulsi…

Effects of Disorder on Charge Orderings and Superconductivity in the System of Coexisting Itinerant Electrons and Local Pairs
Stanisław Robaszkiewicz, Grzegorz Pawłowski
We study the phase diagrams and thermodynamic properties of a system of coexisting itinerant electrons and local pairs (LP), in the presence of diagonal disorder. The model conside…
