Analysis of the Forward and Reverse Strongly Coupled States on the Nonradiative Energy Transfer Effect

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.

Automated summary

In this study, it was found that resonance between cavity mode and donor/acceptor can promote energy transfer, but the polariton-mediated energy transfer mechanisms behind different strong coupling systems are different. The time evolution of the mean photon number of each polariton state under different strongly coupled states were calculated using the quantum Tavis-Cummings theory to analyze the energy transfer effect.
