Abstract
While the majority opinion in the field of high-temperature superconductivity has been that the electron-phonon coupling is irrelevant to the mechanism of superconductivity, recent experimental results suggest otherwise. We show that in the cuprates the electron-phonon coupling is unconventional, and suggest that the Cu-O bond-stretching LO phonons may play a crucial role in superconductivity through formation of a vibronic bound state.
