Title: A Mean Field Approach For An Extended Hubbard Model With Correlated Hopping: Interplay Of Antiferromagnetism And Superconductivity
Author: Lara G.A.
Cabrera G.G.
Abstract: An extended Hubbard model, including Coulomb repulsion and correlated hopping between nearest neighbors, is studied using a mean field approach. Superconducting solutions are tested in the presence of antiferromagnetism, near to and away from half filling. Competition between on-site and intersite repulsions, modulated by correlated hopping, yields a covalent bond configuration with partial intrasite and intersite pairings. In addition, antiferromagnetism induces mixed s- and p-type pairing, and superconductivity is completely suppressed by the saturation of the staggered magnetic moment. © 1992.
