Tuning resonance energy transfer with magneto-optical properties of graphene

We investigate the resonance energy transfer (RET) rate between two quantum emitters near a graphene sheet under the influence of a magnetic field. We show that, due to its extraordinary magneto-optical response, graphene allows for an unprecedented (and active) control of the RET. Moreover, we demonstrate that the RET rate is extremely sensitive to small variations of the magnetic field, and can be tuned up to a striking six orders of magnitude, even for quite realistic values of the magnetic field. Our results suggest that magneto-optical media may take the manipulation of energy transfer between quantum emitters to a whole new level, and broaden even more its great spectrum of applications.
