Sum rules and vertex corrections for electron-phonon interactions
O. Rösch, G. Sangiovanni, O. Gunnarsson
We derive sum rules for the phonon self-energy and the electron-phonon contribution to the electron self-energy of the Holstein-Hubbard model in the limit of large Coulomb interact…

Electron-phonon interaction and antiferromagnetic correlations
G. Sangiovanni, O. Gunnarsson, E. Koch +2
We study effects of the Coulomb repulsion on the electron-phonon interaction (EPI) in a model of cuprates at zero and finite doping. We find that antiferromagnetic correlations str…
