Anisotropic Electron-Phonon Interaction in the Cuprates
Anisotropic Electron-Phonon Interaction in the Cuprates
We explore manifestations of electron-phonon coupling on the electron spectral function for two phonon modes in the cuprates exhibiting strong renormalizations with temperature and doping. Applying simple symmetry considerations and kinematic constraints, we find that the out-of-plane, out-of-phase O buckling mode (B(1g)) involves small momentum transfers and couples strongly to …
