Abstract

On the basis of the ideas of Kohn and Luttinger we study superconductivity in purely repulsive Fermi-systems at low density. We obtain superconductive critical temperatures in different 3D and 2D models. These results are important in connection with an experimental search of superconductivity in simple and noble metals, heterostructures and superlattices, together with the layered compounds such as dichalcogenides and Sr2RuO4. We provide an elegant way to increase Tc already at low density in the presence of a strong magnetic field or in a two-band situation.
