TL;DR: A simple and intuitive picture that describes the plasmon response of complex nanostructures of arbitrary shape is presented, an electromagnetic analog of molecular orbital theory, that can be understood as the interaction or "hybridization" of elementary plasmons supported by nanostructure of elementary geometries.

Abstract: We present a simple and intuitive picture, an electromagnetic analog of molecular orbital theory, that describes the plasmon response of complex nanostructures of arbitrary shape. Our model can be understood as the interaction or "hybridization" of elementary plasmons supported by nanostructures of elementary geometries. As an example, the approach is applied to the important case of a four-layer concentric nanoshell, where the hybridization of the plasmons of the inner and outer nanoshells determines the resonant frequencies of the multilayer nanostructure.

Multiple plasmon excitations in adsorbed two-dimensional systems.
TL;DR: Using monolayer graphene as a model system for a purely two-dimensional (2D) electron gas, it is shown that there is a significant probability for the excitation of not only one but two dispersing losses.
