Paper Abstract

For nanostructures such as semiconductor quantum dot emitters or biological systems like light harvesting complexes (photosynthesis) the coupling between individual constituents leads to the formation of delocalized exciton states. Coherent two dimensional spectroscopy is a versatile tool to investigate the structure of the excitonic states, whereas nanoplasmonics allows to localize optical fields on a nanoscale: We combine these two methods in a theoretical study and propose new experiments, such as the two dimensional spectra containing spatial resolution via localized fields. Using post processing of different spectra with localized fields, we can enhance certain spectroscopic features in standard coherent spectroscopy, e.g. by suppressing unwanted resonances.
