平衡费米黄金法则(FGR)速率常数通常用于模拟各种分子系统中的电子能量和电荷转移过程的动力学。电子自由度和腔模式之间的相互作用可以修改当分子系统被放置在腔内时电子状态之间的耦合,从而改变相应的FGR速率常数。在本文中,我们提出了一个通用的框架,估计腔诱导的平衡FGR速率常数的影响。我们表明,腔修改的平衡FGR速率常数可以估计从输入可完全从模拟的无腔的分子系统,从而绕过需要明确的模拟腔内的分子系统。这个框架的有用性证明在马库斯理论极限的平衡FGR,并得出一般规则,用于确定腔诱导马库斯理论速率增强的最佳条件。
Equilibrium Fermi’s golden rule (FGR) rate constants are commonly used for modeling the kinetics of electronic energy and charge transfer processes in a wide range of molecular systems. The interaction between the electronic degrees of freedom and cavity modes can modify the coupling between electronic states when the molecular system is placed inside a cavity, and thereby alter the corresponding FGR rate constants. In this paper, we present a general-purpose framework for estimating the cavity-induced effect on equilibrium FGR rate constants. We show that cavity-modified equilibrium FGR rate constants can be estimated from inputs obtainable exclusively from a simulation of the cavity-free molecular system, thereby bypassing the need for an explicit simulation of the molecular system inside the cavity. The usefulness of this framework is demonstrated in the Marcus theory limit of equilibrium FGR, and general rules are derived for determining the optimal conditions for cavity-induced Marcus theory rate enhancement.
