论文摘要
我们使用偏振态来描述量子电动力学中的耦合分子 - 腔杂种系统。分子永久性偶极子通过取代其矢量电势来使光子场偏振，从而导致两个不同极化光子场的Fock状态之间的非正交性。这些极化的Fock状态可以直观地理解超出量子Rabi模型预测的几种新现象，同时，还提供了数值便利以融合结果。我们进一步利用这种非正交性来从单个电子激发（下调）产生多个光子并控制光化学反应性。
We use the polarized Fock states to describe the coupled molecule-cavity hybrid system in quantum electrodynamics. The molecular permanent dipoles polarize the photon field by displacing its vector potential, leading to non-orthogonality between the Fock states of two different polarized photon fields. These polarized Fock states allow an intuitive understanding of several new phenomena that go beyond the prediction of the quantum Rabi model, and at the same time, offer numerical convenience to converge the results. We further exploit this non-orthogonality to generate multiple photons from a single electronic excitation (downconversion) and control the photochemical reactivity.
