A Novel Theory for High Temperature Superconductors considering Inhomogeneous Charge Distributions
E. V. L. de Mello, E. S. Caixeiro, J. L. Gonzaléz
We present a percolation theory for the high- oxides pseudogap and dependence on the hole level. The doping dependent inhomogeneous charge structure is modeled by a dist…

The Hubbard model applied to the phase diagram and pressure effects in YBa_2Cu_3O_{7-δ} superconductors
E. S. Caixeiro, E. V. L. de Mello
We apply a method based on a BCS-type approach to the extended Hubbard model to deal with the YBa_2Cu_3O_{7-δ} superconductor family under pressure. The parameters of the tight-bin…
