Acoustic plasmons in extrinsic free-standing graphene by M Pisarra, A Sindona, P Riccardi, V M Silkin, J M Pitarke

“…This anisotropy allows for the coexistence of carriers moving with two distinct Fermi velocities along the $\Gamma {\rm K}$ and $\Gamma {\rm K}^{\prime} $ directions, which leads to two modes of collective oscillation: one mode in which the two types of carriers oscillate in phase with one another (this is the conventional 2D graphene plasmon, which at long wavelengths ( $q\to 0$ ) has the same dispersion, ${{q}^{1/2}}$ , as the conventional 2D plasmon of a 2D free electron gas), and the other mode found here corresponds to a low-frequency acoustic oscillation (whose energy exhibits at long-wavelengths a linear dependence on the 2D wavenumber q ) in which the two types of carriers oscillate out of phase. …”
