Colloquium

Superconductivity from repulsive interactions

Andrey Chubukov
Department of Physics, University of Wisconsin-Madison

The theory of superconductivity, for which Nobel Prize was given in 1972, named electron-phonon interaction as a glue that overcomes Coulomb repulsion and binds fermions into pairs which then condense and super-conduct. I review recent and not so recent works aiming to understand whether a nominally repulsive Coulomb interaction can by itself give rise to a superconductivity. I first discuss a generic scenario of the pairing by electron-electron interaction, put forward by Kohn and Luttinger back in 1965 in their attempt to explain superfluidity in 3He, and then move to discuss modern studies of the electronic mechanisms of superconductivity in the cuprates, Fe-pnictides, and in doped graphene.
