Abstract

Coupling between copper d_θ and d_ε states in cuprates leads to a pairing mechanism that has the same form, but opposite sign, to that of BCS theory. It is stable against lattice distortion even for strong coupling. The nature of the interaction (Jahn-Teller type or an excitonic process having similar symmetries) is considered.
