Superconductivity in the Hubbard model with pair hopping
Stanislaw Robaszkiewicz, Bogdan R. Bulka
The phase diagrams and superconducting properties of the extended Hubbard model with pair hopping interaction, i.e. the Penson-Kolb-Hubbard model are studied. The analysis of the m…

Superconductivity in the Hubbard model with correlated hopping: Slave-boson study
Bogdan R. Bulka
The slave boson mean-field studies of the ground state of the Hubbard model with correlated hopping were performed. The approach qualitatively recovers the exact results for the ca…
