Description
A detailed study of the excitation spectrum of single-layer and multilayer graphene is investigated within the RPA approximation, including different kinds of disorder. In the presence of a quantizing magnetic field, the spectrum reveals an unusual particle-hole spectrum. A theoretical description of Bernstein modes arising from the coupling between plasmon and inter-Landau-level excitations is presented. Spin-reversal excitations are also considered.
