Abstract: Optical properties of low-dimensional materials are strongly governed by excitons and their interactions with defects. For instance, non-radiative exciton decays in carbon nanotubes are presumably happened at defects and result in the low luminescence quantum… read more here.

Abstract: The bottom-up fabrication of graphene nanoribbons (GNRs) has opened new opportunities to specifically tune their electronic and optical properties by precisely controlling their atomic structure. Here, we address excitation in GNRs with periodic structural wiggles,… read more here.

Abstract: The interaction of light with solids gives rise to new bosonic quasiparticles, with the exciton being-undoubtedly-the most famous of these polaritons. While excitons are the generic polaritons of semiconductors, we show that for strongly correlated… read more here.
