Superconductivity from repulsive interactions in the two dimensional electron gas
arXiv:1009.3600 · doi:10.1103/PhysRevB.83.094518
Abstract
We present a well-controlled perturbative renormalization group (RG) treatment of superconductivity from short-ranged repulsive interactions in a variety of model two dimensional electronic systems. Our analysis applies in the limit where the repulsive interactions between the electrons are small compared to their kinetic energy.
