Enhancing Resonance Energy Transfer by Means of Coherence and Entanglement — •Severin Bang1, Robert Bennett1, and Stefan Yoshi Buhmann1,2 — 1Institute of Physics, University of Freiburg, Germany — 2Freiburg Institute for Advanced Studies (FRIAS), Germany
Resonance energy transfer usually refers to a transfer between two partners. In this talk, we explore how the process can be enhanced by replacing a single donor by an entangled donor system coherently sharing excitations. We demonstrate this for the example of donors initially prepared in a superradiant Dicke state.
We describe the process by quantum electrodynamics in terms of dipole moments coupled via an exchange of virtual photons, whose propagation is encoded in Green’s tensors . We focus on the possibility of enhancing the energy transfer rate and on its dependence on the spacial configurations of donors and acceptors.
