光-物质强耦合作用下的非辐射能量传递（NRET）为实现超长距离、超快的能量传递提供了一种有效的方法，这对于实现远程控制化学和生物大分子相互作用的实时动态研究等都具有重要意义.本文证明了腔模不仅可以先与施主共振形成级联混合光场，物质态驱动能量转移，当腔模首先与受体共振时，它也可以增强施主和受体之间的非辐射能量转移。重要的是，虽然这两个强耦合系统可以增强能量转移，但这些过程背后的极化激元介导的能量转移机制是不同的。利用量子Tavis-Cummings理论，计算了各极化激元态的平均光子数随时间的演化，分析了不同强耦合态下的能量转移效应。
Nonradiative energy transfer (NRET) under light–matter strong coupling interaction provides an efficient method to achieve the ultralong-distance and ultrafast energy transfer, which is of significance in realizing remote control chemistry and the real-time dynamic research of biological macromolecules interaction and so on. Here we show that not only can the cavity mode first resonate with the donor to form a cascade hybrid light–matter states to drive energy transfer, when the cavity mode first resonates with the acceptor, it also can enhance the nonradiative energy transfer between the donor and the acceptor. Importantly, although these two strong coupling systems can enhance energy transfer, the polariton-mediated energy transfer mechanism behind these processes is different. By employing the quantum Tavis–Cummings theory, we calculate the time evolution of the mean photon number of each polariton state to analyze the energy transfer effect under different strongly coupled states.
