Superluminal plasmons with resonant gain in population inverted bilayer graphene
arXiv:1712.09924 · doi:10.1103/PhysRevB.98.041403
Abstract
AB-stacked bilayer graphene with a tunable electronic bandgap in excess of the optical phonon energy presents an interesting active medium, and we consider such theoretical possibility in this work. We argue the possibility of a highly resonant optical gain in the vicinity of the asymmetry gap. Associated with this resonant gain are strongly amplified plasmons, plasmons with negative group velocity and superluminal effects, as well as directional leaky modes.
