1. Plasmons in Nanostructured Graphene
Abstract : Plasmons, collective electron density oscillations, provide physicists with intriguing challenges and possibilities. The inherent many-body properties of the plasmons together with their ability to localize light into small volumes make the plasmons interesting from both a purely theoretical viewpoint and an applications point of view.

5. Optical properties of active photonic materials
Abstract : Because of the generation of polaritons, which are quasiparticles possessing the characteristics of both photonics and electronics, active photonic materials offer a possible solution to transfer electromagnetic energy below the diffraction limit and further increase the density of photonic integrated circuits. A theoretical investigation of these exciting materials is, therefore, very important for practical applications. READ MORE
