Electron-Phonon Coupling in Strongly Correlated Electron Systems
The electron-phonon coupling is discussed in the framework of the Bogolubov method. Due to imperfect screening in the high-Tc oxides, fluctuations of the crystal field and fluctuations of the Coulomb field are the main contributions to the electronphonon interaction in ionic metals with strongly correlated electrons.
