Superconducting Order Parameters in the Extended Hubbard Model: A Simple Mean-Field Study

Das, Mukunda P; Thakur, Jagdish S


The extended Hubbard model with nearest neighbor hopping and intersite interaction for a 2D square lattice has been studied within the frame work of a simple mean-field formalism, The self-consistent solutions of superconducting order parameters have been obtained for various fillings. The results indicate that superconducting pairing occurs on doping for the repulsive on-site U and attractive nearest neighbor V.
