Zusammenfassung der Projektergebnisse

The aim of this project was elucidating the onset of the quantum plasmonic effect. However, unexpected new results (the LBDP mode blue-shift of non-ideal dimer) in the classical regime were found. To find the reason, we investigated (i) which factors make ideal dimers plasmonically different from non-ideal dimers (conventionally prepared experimental dimers) and (ii) why ideal dimers are essential for comparison with theoretical models. We emphasize that the original objectives of the project can be conducted after finishing it.
