Abstract

Abstract In the frame of the Hartree–Fock approximation, the dispersion of magnetoplasmons in Graphene is derived for transitions implying the n = 0 Landau Level and those corresponding to the electron–hole transitions. It is shown that the electron–electron interactions lead to a strong re-normalization of the apparent Fermi velocity of Graphene which is different for both types of transitions.
