论文摘要
我们通过直接或通过空腔模式定期驾驶红外活性振动过渡来讨论耗散分子系统的浮雕工程。遵循极性量子Langevin方程方法，我们得出相关函数和固定量，显示了红外线分子的强烈修饰的光学响应。分子振动模式的一致激发，结合由于振动耦合而引起的电子自由度的调节，可以导致增强的振动连贯性以及对振动侧带振幅的控制。与红外腔的额外耦合允许受控抑制不希望的边带，这是振动弛豫率增强的效果。
We discuss Floquet engineering of dissipative molecular systems through periodic driving of an infrared-active vibrational transition, either directly or via a cavity mode. Following a polaron quantum Langevin equations approach, we derive correlation functions and stationary quantities showing strongly modified optical response of the infrared-dressed molecule. The coherent excitation of molecular vibrational modes, in combination with the modulation of electronic degrees of freedom due to vibronic coupling can lead to both enhanced vibronic coherence as well as control over vibrational sideband amplitudes. The additional coupling to an infrared cavity allows for the controlled suppression of undesired sidebands, an effect stemming from the Purcell enhancement of vibrational relaxation rates.
