Collective effects in resonance energy transfer phenomena — •Severin Bang1, Robert Bennett1, and Stefan Yoshi Buhmann1,21Institute of Physics, University of Freiburg, Germany — 2Freiburg Institute for Advanced Studies (FRIAS), Germany

Resonance energy transfer usually refers to a transfer between two partners. Superradiance is a collective decay effect, in which an ensemble of atoms emits radiation into its environment. In this talk, we explore the possibility of combining these two phenomena to potentially enhance the efficiency of energy transfer by introducing superradiant ensembles of donors and/or acceptors.

The process is described by quantum electrodynamics in terms of dipole moments coupled via an exchange of virtual photons, whose propagation is encoded in Green’s tensors [1]. We focus on the possibility of enhancing the energy transfer rate and on its dependence on the spacial configurations of donors and acceptors.
