    • note
    • Contact interaction has been considered in Ref. as the dominant Raman scattering mechanism in graphene. Such an assumption is justified for scattering of soft x-rays with energies Ω > 6 γ 0 ∼ 10 eV larger than the bandwidth in this material. However, as shown here, for photons in the visible range (with energies Ω ∼ (1 ÷ 2) eV < γ 0) such an assumption would lead to incorrect symmetry of the excitations, polarisation properties of the Raman signal, and selection rules for the dominant inter-LL excitations. Although for a zero magnetic field the spectral density of inelastically scattered light found in Ref. and in the present study may look similar, which is because it coincides with the density of state of zero-momentum electron-hole excitations in graphene, the use of contact interaction alone underestimates the intensity of Raman scattering of visible light by two orders of magnitude. However, such term is important to take into account [among many others (Ref.)] in the analysis of the quantum efficiency of the excitation of the Γ -point optical phonon.
