Abstract

A model interaction is proposed in which pairing is caused by a nonlocal Jahn-Teller-like instability due to the coupling between planar O states and k\ensuremath≠0 phonons. Apart from pairing, the interaction is found to naturally allow metallic stripe formation. The consequences of the model for superconductivity in the cuprates are discussed. The model is shown to be consistent with numerous sets of experimental data in quite some detail.
