Magnetic field induced rotation of the d-vector in Sr_2RuO_4
J. F. Annett, G. Litak, B. L. Gyorffy +1
The superconductor Sr_2RuO_4 is widely believed to be a spin triplet system with a chiral order parameter analogous to the A phase of superfluid helium-3. The best evidence for thi…
Superconducting Pairing Amplitude and Local Density of States in Presence of Repulsive Centers
Grzegorz Litak, Mariusz Krawiec
We study the properties of superconductor in presence of a finite concentration of repulsive centers. The superconductor is described by the negative Hubbard model while repuls…
'Pi State' Induced by Impurities with a Repulsive Interaction
Grzegorz Litak, Mariusz Krawiec
We study the properties of a quantum impurity embedded in a superconducting host. The superconductor is described by the negative U Hubbard model while the impurity introduces a re…
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…
