Exotic pairing via a central attraction: from the BCS to the Bose limits
J. Quintanilla, B. L. Gyorffy, J. F. Annett +1
In the context of a simple model featuring an explicit, central interaction potential, and using a standard functional-integral technique, we study superconductivity with angular m…
BCS to Bose Crossover in Anisotropic Superconductors
J. P. Wallington, James F. Annett
In this work we use functional integral techniques to examine the nearest neighbour attractive Hubbard model on a quasi-2D lattice. It is a simple phenomenological model for the hi…
S- and D-Wave Pairing in Short Coherence Length Superconductors
James F. Annett, Jonathan P. Wallington
We derive an appropriate Landau-Ginzburg-Wilson effective action to describe the nearest neighbour attractive Hubbard model. This allows us to discuss both the small V (BCS) limit…
Discrete Symmetries and Transformations of the Hubbard Model
Jonathan P. Wallington, James F. Annett
We show that, in addition to SO(4), the Hubbard model at half filling on a bipartite lattice has a group of discrete symmetries and transformations. A unique Hubbard-Stratonovich d…
