Pre-formed Cooper pairs and Bose-Einstein condensation in cuprate superconductors
M. Casas, M. de Llano, A. Puente +2
A two-dimensional (2D) assembly of noninteracting, temperature-dependent, pre-formed Cooper pairs in chemical/thermal equilibrium with unpaired fermions is examined in a binary bos…
Two-dimensional Bose-Einstein Condensation in Cuprate Superconductors
M. Casas, M. de Llano, A. Puente +2
Transition temperatures calculated using the BCS model electron-phonon interaction without any adjustable parameters agree with empirical values for quasi-2D cuprate superc…
Statistical Model of Superconductivity in a 2D Binary Boson-Fermion Mixture
M. Casas, N. J. Davidson, M. de Llano +5
A two-dimensional (2D) assembly of noninteracting, temperature-dependent, composite-boson Cooper pairs (CPs) in chemical and thermal equilibrium with unpaired fermions is examined…
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…
