论文摘要
我们研究了在外部磁场的影响下，在真空中悬浮的石墨烯片附近的两个量子发射器之间的共振能量转移（RET）速率。我们对低室温和室温进行分析，并表明，由于石墨烯的非凡磁光响应，即使在室温的情况下，它也可以进行RET的主动控制和可调性。我们还证明，RET速率对所施加的磁场的较小变化非常敏感，并且可以将其调整为六个巨大的六个数量级，以实现磁场的非常逼真的值。此外，我们证明了石墨烯单层支持的磁极极化子作为在一定距离范围内的主要通道所起的基本作用。我们的结果表明，磁光介质可能会将量子发射器之间的能量转移操纵达到一个全新的水平，并扩大其极大的应用范围。
We investigate the resonance energy transfer (RET) rate between two quantum emitters near a suspended graphene sheet in vacuum under the influence of an external magnetic field. We perform the analysis for low and room temperatures and show that, due to the extraordinary magneto-optical response of graphene, it allows for an active control and tunability of the RET even in the case of room temperature. We also demonstrate that the RET rate is extremely sensitive to small variations of the applied magnetic field, and can be tuned up to a striking six orders of magnitude for quite realistic values of magnetic field. Moreover, we evidence the fundamental role played by the magnetoplasmon polaritons supported by the graphene monolayer as the dominant channel for the RET within a certain distance range. 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.
