The Kohn-Luttinger mechanism for superconductivity is investigated in a model for the electron-doped cuprates. The symmetry of the order parameter of the superconducting phase is determined as a function of the geometry of the Fermi surface together with the structure of the electron-hole susceptibility. It is found to remain d x 2 - y 2 wave within a large doping range. The shape of the gap anisotropy evolves with doping, with the maximum gap moving away from (π,0), in good agreement with… Expand

Pairing in the two-dimensional Hubbard model from weak to strong coupling
The Hubbard model is the simplest model that is believed to exhibit superconductivity arising from purely repulsive interactions, and has been extensively applied to explore a variety ofExpand
