Energy transfer and interference by collective electromagnetic coupling
The physics of collective optical response of molecular assemblies,pioneered by Dicke in 1954, has long been at the center of theoretical andexperimental scrutiny. The influence of the environment on such phenomena isalso of great interest due to various important applications in, e.g., energyconvers...

| Resumo: | The physics of collective optical response of molecular assemblies,pioneered by Dicke in 1954, has long been at the center of theoretical andexperimental scrutiny. The influence of the environment on such phenomena isalso of great interest due to various important applications in, e.g., energyconversion devices. In this Letter, we demonstrate both experimentally andtheoretically the spatial modulations of the collective decay rates of moleculesplaced in proximity to a metal interface. We show in a very simple framework howthe cooperative optical response can be analyzed in terms of intermolecularcorrelations causing interference between the response of different molecules andthe polarization induced on a nearby metallic boundary and predict similarcollective interference phenomena in excitation energy transfer betweenmolecular aggregates |
