The effect of strong Coulomb correlations on electron-phonon interactions in the copper oxides: Implications for transport
Description:
The effects of strong Coulomb correlations on the electron-phonon interactions in the high temperature superconductors are investigated. Very strong Coulomb correlations, which are essential for creating the insulating state at half filling, lead to a suppression of charge fluctuations as the insulator is approached. This thereby significantly reduces the electron-phonon coupling. We present a self-consistent frozen phonon'' scheme which is based on a Coulomb renormalized band structure of the …
