  • BCS and Bose-Einstein condensates in superconductivity and superfluidity
    Grether, M; Fortes, M; Sevilla, FJ; Solis, MA; de Llano, M; Salazar, A; Valladares, AA; Rojo, O (2001)
  • Bose-Einstein condensation in the relativistic ideal Bose gas
    Grether, M; de Llano, M; Baker, GA (2007)
    The Bose-Einstein condensation (BEC) critical temperature in a relativistic ideal Bose gas of identical bosons, with and without the antibosons expected to be pair-produced abundantly at sufficiently hot temperatures, is ...
  • Free and trapped Fermi gases: Some novel results
    Grether, A; Fortes, M; Sevilla, FJ; Solis, MA; Tapia, S; de Llano, M; Valladares, AA; Tolmachev, VV (2000)
  • Generalized BEC in superconductivity
    Grether, A; de Llano, M (2007)
    A generalized Bose-Einstein condensation (GBEC) statistical theory of superconductors accounts not for BB interactions but rather for boson-fermion (BF) interactions. It extends the 1989 Friedberg-Lee BEC theory by including ...
  • Harmonically trapped ideal quantum gases
    Grether, M; Fortes, M; de Llano, M; del Rio, JL; Sevilla, FJ; Solis, MA; Valladares, AA (2003)
    We solve the problem of a Bose or Fermi gas in d-dimensions trapped by delta < d mutually perpendicular harmonic oscillator potentials. From the grand potential we derive their thermodynamic functions (internal energy, ...
  • INTRIGUING ROLE OF HOLE-COOPER-PAIRS IN SUPERCONDUCTORS AND SUPERFLUIDS
    Grether, M; de Llano, M; Ramirez, S; Rojo, O (2009)
    The role in superconductors of hole-Cooper-pairs (CPs) are examined and contrasted with the more familiar electron-CPs, with special emphasis on their "background" effect in enhancing superconducting transition temperatures ...
  • Low-dimensional BEC
    Sevilla, FJ; Grether, M; Fortes, M; de Llano, M; Rojo, O; Solis, MA; Valladares, AA (2000)
    The Bose-Einstein condensation (BEC) temperature T-c of Cooper pairs (CPs) created front a general interfermion interaction is determined for a linear, as well as the usually assumed quadratic, energy vs center-of-mass ...
  • Superconducting transition-temperature enhancement due to electronic-band-structure density-of-states
    Fuentes, V; de Llano, M; Grether, M; Solis, MA (1999)
    We briefly review a simple statistical model of a boson-fermion mixture of unpaired fermions plus linear-dispersion-relation Cooper pairs that leads to Bose-Einstein condensation (BEC) for all dimensions greater than unity. ...
