Obiettivo del progetto (Objective)
'In the strong light-matter interaction regime, a quantum emitter exchanges energy with an electromagnetic resonator in a reversible, coherent manner. In this unique situation the separated wavefunctions of the two entities are no longer the eigenstates of the Hamiltonian and one resorts to a 'dressed atom' approach, where the degenerate energy level splits into two new coupled states. Similarly, dye molecules embedded in a photonic nanostructure may interact resonantly with it to produce a hybrid system with new energetic states known as cavity-polaritons. The formation of such mixed light-matter states is a subject of on-going research since the mid 1980's, studied with atoms, semiconductors, electronic spins in NV centers and more. However, with organic molecules, new opportunities arise, which lay at the interface between physics and chemistry: the creation of new states and the rearrangement of the molecular energy landscape can modify chemical and material properties. This is a new concept, recently introduced, and which may be used for tailoring material properties for specific purposes. In this proposal I will pursue several avenues under the framework of strong interactions of molecules and light, and in particular I will development novel methods to control chemical reactions by strong coupling. I will examine the use of the coupling to plasmonic nanostructures for manipulating the triplet formation in organic dyes. By that I will be able modify the branching ratio for various processes in such molecules – phosphorescence quantum yield or chemical reactions evolving through the triplet state. In addition, I will study the transport properties of molecular films strongly-coupled to surface plasmons, and the spatio-temporal dynamics of such hybrid systems. The generality of the ideas in this proposal makes them significant to a wide range of organic-based systems and applications – light emitting/harvesting devices, photosynthesis, photo-oxidation and more.'
