Abstract EN
The Hubbard-Holstein model is a simple model including both electron-phonon interaction and electron-electron correlations.
We review a body of theoretical work investigating, the effects of strong correlations on the electron-phonon interaction.
We focus on the regime, relevant to high-Tc superconductors, in which the electron correlations are dominant.
We find that electron-phonon interaction can still have important signatures, even if many anomalies appear, and the overall effect is far from conventional.
In particular in the paramagnetic phase the effects of phonons are much reduced in the low-energy properties, while the high-energy physics can still be affected by phonons.
Moreover, the electron-phonon interaction can give rise to important effects, like phase separation and charge-ordering, and it assumes a predominance of forward scattering even if the bare interaction is assumed to be local (momentum independent).
Antiferromagnetic correlations reduce the screening effects due to electron-electron interactions and revive the electron-phonon effects.
