Interplay of Coulomb and electron-phonon interactions in graphene

Published 2007-09-12, updated 2008-01-20Version 2

We consider mutual effect of the electron-phonon and strong Coulomb interactions on each other by summing up leading logarithmic corrections via the renormalization group approach. We find that the Coulomb interaction enhances electron coupling to the intervalley A1 optical phonons, but not to the intravalley E2 phonons.
