Electron-phonon interaction and antiferromagnetic correlations.
We study effects of the Coulomb repulsion on the electron-phonon interaction (EPI) in the Holstein-Hubbard model, using the antiferromagnetic (AF) dynamical mean-field approximation. AF correlations strongly enhance EPI effects on the electron Green's function with respect to the paramagnetic correlated system, but the net effect of the Coulomb interaction is a moderate suppression of the EPI. ...
متن کاملThe Electron-Phonon Interaction in the Presence of Strong Correlations
We investigate the effect of strong electron-electron repulsion on the electronphonon interaction from a Fermi-liquid point of view. In particular we show that the strong interaction is responsible for vertex corrections, which are strongly dependent on the vF q/ω ratio, where vF is the Fermi velocity and q and ω are the transferred momentum and frequency respectively. These corrections generic...
متن کاملA NUMERICAL RENORMALIZATION GROUP APPROACH FOR AN ELECTRON-PHONON INTERACTION
A finite chain calculation in terms of Hubbard X-operators is explored by setting up a vibronic Harniltonian. The model conveniently transformed into a form so that in the case of strong coupling a numerical renormalization group approach is applicable. To test the technique, a one particle Green function is calculated for the model Harniltonian

متن کاملElectron Phonon Interaction and Strong Correlations in High-Temperature Superconductors: One can not avoid unavoidable
The important role of the electron-phonon interaction (EPI) in explaining the properties of the normal state and pairing mechanism in high-Tc superconductors (HTSC) is discussed. A number of experimental results are analyzed such as: dynamical conductivity, Raman scattering, neutron scattering, ARPES, tunnelling measurements, isotope effect and etc. They give convincing evidence that the EPI is...
