Coexistence of superconductivity and charge density wave in a correlated regime
E. J. Calegari, L. C. Prauchner, A. C. Lausmann +1
To investigate the coexistence of superconductivity and charge density wave (CDW) in a correlated regime, we employ the Green's functions formalism, as well as the Hubbard-I approx…

Effects of the Hybridization on the Fermi Surface of an Extended Hubbard Model
E. J. Calegari, S. G. Magalhaes, A. A. Gomes
The Fermi surface (FS) of an extended Hubbard model is investigated by a two-pole approximation in both situations with hole and electron doping. Using the factorization proc…
