Simple model of anisotropic pairing with repulsive interactions
Abstract
A simple tight binding model with repulsive interactions is studied. The inclusion of more than one orbital per site leads to assisted hopping effects, and, when the orbitals involved have different symmetries, to an anisotropic superconducting phase. Superconductivity exists for all fillings, and for all values of the on site repulsion.
