Renormalization of the electron-phonon coupling in the one-band Hubbard model
Erik Koch, Roland Zeyher
We investigate the effect of electronic correlations on the coupling of electrons to Holstein phonons in the one-band Hubbard model. We calculate the static electron-phonon vertex…

Field-doping of C60 crystals: A view form theory
Erik Koch, Olle Gunnarsson, Samuel Wehrli +1
The proposal of using the field-effect for doping organic crystals has raised enormous interest. To assess the feasibility of such an approach, we investigate the effect of a stron…
