Coupled electronic and magnetic excitations in the cuprates and their role in the superconducting transition

Abstract

The pairing mechanism behind the Cooper pairs in unconventional superconductors has been debated since the discovery of the high-Tc cuprates. Here, using angle resolved photoemission spectroscopy data for Bi2212 applied to the Bethe-Salpeter equation, the authors suggest that a spin-mediated pairing interaction can account for the high superconducting temperature as well as play a dominant role in the Cooper pair formation.
