论文摘要
在证明增强,抑制和对化学反应速率的可忽略不计,取决于特定反应和空腔频率,使用光腔来控制化学反应。在这项工作中,我们研究了不完美的腔体内的反应速率,在该腔体中,我们将光谱密度的扩展参数引入了模仿Fabry-Pérot腔。我们使用非马克维亚的兰格文动力学对反应速率进行了对反应速率的修饰,以摩擦和随机力来解释不完美的光腔的存在。我们证明,在弱溶剂和空腔摩擦的状态下,空腔可以提高化学反应速率。另一方面,在高摩擦方面,空腔可以抑制化学反应。此外,我们发现腔光谱密度的扩大会导致共振条件的蓝移,令人惊讶地增加了共振效应的清晰度。
The use of optical cavities to control chemical reactions has been of great interest recently, following demonstrations of enhancement, suppression, and negligible effects on chemical reaction rates depending on the specific reaction and cavity frequency. In this work, we study the reaction rate inside imperfect cavities, where we introduce a broadening parameter in the spectral density to mimic Fabry-Pérot cavities. We investigate cavity modifications to reaction rates using non-Markovian Langevin dynamics with frictional and random forces to account for the presence of imperfect optical cavities. We demonstrate that in the regime of weak solvent and cavity friction, the cavity can enhance chemical reaction rates. On the other hand, in the high friction regime, cavities can suppress chemical reactions. Furthermore, we find that the broadening of the cavity spectral density gives rise to blue shifts of the resonance conditions and, surprisingly, increases the sharpness of the resonance effect.
