Charge and Phase Fluctuations in Attractive Hubbard Model
Grzegorz Litak
Using the negative U Hubbard model we analyze normal state properties of a superconductor. In this model there exists a characteristic pairing temperature T_P above a superconducti…

Superconductivity Induced by Negative Centers
G. Litak, T. Paiva, R. T. Scalettar +2
We study the effect of random dilution of attraction centers on electron pairing in a generalization of the negative Hubbard model where the interaction , defined on the t…

P-wave Pairing in superconducting Sr2RuO4
G. Litak, J. F. Annett, B. L. Gyorffy +1
Two models for the superconducting state of Sr2RuO4 have been analyzed. In an "orbital model" the in-plane and out of-plane interactions between electrons on neighboring Ru atoms a…
