  • 2D and quasi-2D models for Y124 under pressure
    Ortiz, MA; Arredondo, Y; Mendez-Moreno, RM; Orozco, S; Moreno, M (2004)
    Experimentally it is found that the pressure dependence of T-c, in high-T-c superconductors, is influenced by several factors. The carrier density, the doping, and the contraction of the unit cell are some of these factors. ...
  • A model for high-T-c superconductors with energy-band overlapping
    Ortiz, MA; Mendez-Moreno, RM; Orozco, S; Moreno, M (2002)
    The correlation between pressure and the critical temperature of high-T-c superconductors is studied. The specific case of the Hg cuprates is considered in detail. In a simple model in which overlapping of bands increases ...
  • A model for the isotope effect in high-T-c superconductors
    Orozco, S; Ortiz, MA; Mendez-Moreno, RM; Moreno, M (2004)
    In this work the isotope coefficient is calculated from the BCS gap equation, using a model with anomalous occupation in the momentum space. The specific case of cuprate oxide superconductors is considered in detail. The ...
