Enhancing Resonance Energy Transfer by Means of Coherence and Entanglement — •Severin Bang¹, Robert Bennett¹, and Stefan Yoshi Buhmann^1,2 — 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 [1]. We focus on the possibility of enhancing the energy transfer rate and on its dependence on the spacial configurations of donors and acceptors.
