TL;DR: In this article, the authors used a graphene-based magnetic resonator to realize single, nanometer-scale acoustic graphene plasmon cavities, reaching mode volume confinement factors of 5 × 1010.

TL;DR: Graphene–insulator–metal heterostructures show three orders of magnitude enhancement of the third-harmonic generation with respect to the bare graphene case, and are shown to be a promising heterostructure for optically controlled and electrically tunable nano-optoelectronic components.

TL;DR: In this article, the authors report record enhancement of high-harmonic generation and demonstrate, for the first time, that plasmons can indeed affect the graphene nonlinear optical response, which can confine the optical field down to the atomic level.

TL;DR: In this article, the authors demonstrate a new way to excite acoustic-graphene-plasmons (AGPs) that are confined to nanometric-scale cavities directly from the far-field, via localized graphene-plasmon-magnetic-resonators (GPMRs).
