Pair fluctuation effects above $T_{c}$

J. J. Rodríguez-Núñez, S. Schafroth, R. Micnas +3

We explore the occurrence of pairing effects above $T_{c}$ in the 2D attractive Hubbard model. The presence of pairs above $T_{c}$ 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 $T \geq T_{c}$ 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 $k_{F} ξ$ 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- $T_{c}$ cuprates. Their short cohere…
