Pseudogap Phenomena and Superconducting Fluctuations in Hubbard Model for High-<i>T</i><sub>c</sub>Cuprates
The pseudogap phenomena in High- T c cuprates are investigated on the basis of the Hubbard model which includes only the on-site repulsive interaction U . We consider the pairing scenario for the pseudogap. The pseudogap arises from the resonance scattering due to the strong superconducting fluctuations. First, the electronic …
