We will review recent advances in the control and understanding of plasmons in
systems that have atomic dimensions along one or more directions. In
particular, we will discuss plasmons in graphene, carbon nanotubes, and
fullerenes, as well as thin metal layers and molecules such as polycyclic
aromatic hydrocarbons. A simple, powerful, analytical eigenmode expansion
formalism will be reviewed in the electrostatic limit, along with tutorial
examples of application to the understanding of plasmons in these systems,
including the derivation of approximate expressions for the plasmon
frequencies and wave functions. Intrinsic advantages of plasmons in atomic-
scale systems will be also discussed, and in particular, theie large
electrical tunability, their strong nonlinear response, and the possibility of
reaching quantum strong coupling.
