It has been a pleasure to get to know in person Francisco Garcia Vidal, who leads the Plasmonics Group at the Universidad Autonoma de Madrid. Francisco gave the Faculty Kolloquium and presented the foundations of this subject, the state of the art concerning plasmon generation and transmission and finalized his talk with a glimpse of the interesting work of his group in the context of exciton transport. Recently, Garcia Vidal and his group have shown that exciton conductance in organic materials can be largely enhanced when the molecules are strongly coupled to an electromagnetic mode. This is a result that could be relevant for the dynamics of photosynthetic systems in which exciton transport plays a key role. You can read further details in Phys. Rev. Lett. 114, 196402 (2015).
After the talk, and as small compensation for the long trip in a day that is festive in Spain, we continued the discussions in a relaxed environment and took Francisco to sample the local cuisine and try out delicious home made Spaetzle.
