Harmonically Trapped Quantum Gases
M. Grether, M. Fortes, M. de Llano +4
We solve the problem of a Bose or Fermi gas in -dimensions trapped by mutually perpendicular harmonic oscillator potentials. From the grand potential we derive their…
Bose-Einstein condensation of nonzero-center-of-mass-momentum Cooper pairs
J. Batle, M. Casas M. Fortes, M. A. Solís +3
Cooper pair (CP) binding with both zero and nonzero center-of-mass momenta (CMM) is studied with a set of renormalized equations assuming a short-ranged (attractive) pairwise inter…
Linear to quadratic crossover of Cooper pair dispersion relation
S. K. Adhikari, M. Casas, A. Puente +6
Cooper pairing is studied in three dimensions to determine its binding energy for all coupling using a general separable interfermion interaction. Also considered are Cooper pairs…
Superconductivity as a Bose-Einstein condensation?
S. K. Adhikari, M. Casas, A. Puente +6
Bose-Einstein condensation (BEC) in two dimensions (2D) (e.g., to describe the quasi-2D cuprates) is suggested as the possible mechanism widely believed to underlie superconductivi…
Cooper pair dispersion relation for weak to strong coupling
S. K. Adhikari, M. Casas, A. Puente +6
Cooper pairing in two dimensions is analyzed with a set of renormalized equations to determine its binding energy for any fermion number density and all coupling assuming a generic…
