Description of molecular nanomagnets by the multi-orbital Hubbard model with correlated hopping
Jacek Matysiak, Romuald Lemański
We present a microscopic description of molecular magnets by the multi-orbital Hubbard model, which includes the correlated hopping term, i.e. the dependence of electron hopping am…

Extended Falicov-Kimball model at weak onsite and intersite Coulomb interactions
K. J. Kapcia, J. Krawczyk, R. Lemański
We analyze in detail a behavior of the order parameter in the half-filled extended Falicov-Kimball model for small Coulomb interactions (both onsite and intersite ). The par…
