Compressibility of a two-dimensional extended Hubbard model

E. J. Calegari, S. G. Magalhães, A A. Gomes

The compressibility of an extended Hubbard model is investigated by the Roth's two-pole approximation. Using the factorization procedure proposed by Beenen and Edwards, super…

Superconductivity in a two dimensional extended Hubbard model

E. J. Calegari, S. G. Magalhaes, A. A. Gomes

The Roth's two-pole approximation has been used by the present authors to investigate the role of hybridization in the superconducting properties of an extended Hubbard…
