Condensation of Hard-Core Pairs on a Lattice: A Model of the Superconducting State in Cuprates
Morten Holm Pedersen, Toni Schneider
Using the Monte Carlo technique we study the dependence of transition temperature, penetration depth and specific heat singularity on the pair concentration in the Bose Hubbard mod…
Pair fluctuation effects above
J. J. Rodríguez-Núñez, S. Schafroth, R. Micnas +3
We explore the occurrence of pairing effects above in the 2D attractive Hubbard model. The presence of pairs above goes beyond the BCS approximation, in whi…
Evidence for a Pseudogap Above the Critical Temperature in the Attractive Hubbard Model
J. J. Rodríguez-Núñez, S. Schafroth, R. Micnas +3
We explore the effect of fluctuations for in the 2-D negative Hubbard model within the framework of the selfconsistent T-matrix formalism, which goes beyond the BCS ap…
Comment on "Evolution from BCS Superconductivity to Bose-Einstein Condensation: Role of the Parameter in Interpreting the Experimental Plot by Uemura et al.''}
J. J. Rodríguez-Núñez, S. Schafroth, T. Schneider +2
The problem of crossover from BCS to Bose-Einstein condensation has recently attracted considerable interest owing to the discovery of high- cuprates. Their short cohere…
