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…
