论文摘要
我们研究了硅质分子的解离动力学，以莫尔斯振荡器为模型，耦合到光腔。在经典和量子动力学模拟中，观察到对分解频率的分离概率的明显抑制，显着低于分子的基本过渡频率。我们表明，当分子的经典相空间中的某些关键非线性共振消失时，仅当偶极子函数是非线性时才可能发生的概率的抑制。这项研究表明，腔内分子振动能量转移在非谐波极限中的复杂性，并表明需要进一步的研究以了解振动式极化化学实验中的共振效应。
We study the dissociation dynamics of a diatomic molecule, modeled as a Morse oscillator, coupled to an optical cavity. In both classical and quantum dynamics simulations, a marked suppression of the dissociation probability is observed for cavity frequencies significantly below the fundamental transition frequency of the molecule. We show that the suppression in the probability occurs when certain key nonlinear resonances in the classical phase space of the molecule disappear, possible only when the dipole function is nonlinear. This study demonstrates the complexity of cavity-molecule vibrational energy transfer in the anharmonic limit and suggests further studies are necessary to understand resonance effects in experiments of vibrational polariton chemistry.
