Relevance of electron-phonon coupling in high-T c superconductors

Abstract

The experimental observation of phonon renormalization in high-Tc superconductors gives clear evidence for the action of electron-phonon coupling. But in spite of the estimated coupling strength λ ∼ 1–3, these effects do not allow for a unique identification of the coupling mechanism. This situation is contrasted with that for the low-Tc superconductors where tunneling spectroscopy provides a hard proof for electron pairing via phonons.
