论文摘要
我们研究了Jahn-Teller（JT）Polaritons，它从两个正常的电磁模式与JT活性系统的Fabry-Perrot腔谐振器中的垂直极化器的相互作用出现。这些JT极性子的特征是混合$（+/-）$ - 圆形电磁极化，该偏振源自材料子系统的分子JT振动耦合。因此，光子和振动角动量的交换可能非常有效。激发具有短而极化的光脉冲的空腔-JT系统会导致腔介质中极化的动态和振荡响应。由于光子振动耦合，我们展示了腔极化方向如何变得频率取决于频率，并且不一定与用于驱动系统的外部磁场的极化方向相吻合。
We investigate Jahn-Teller (JT) polaritons, which emerge from the interaction of the two normal-incidence electromagnetic modes with perpendicular polarizations in a Fabry-Perot cavity resonator with JT active systems. These JT polaritons are characterized by a mixed $(+/-)$--circular electromagnetic polarization that originates from the molecular JT vibronic coupling of the material subsystem. Consequently, the exchange of photonic and vibronic angular momenta can be very efficient; exciting the cavity-JT system with short, polarized light pulses results in a dynamical and oscillatory response of the polarization in the cavity medium. Due to the photonic-vibronic coupling, we show how the cavity polarization direction becomes frequency dependent and does not necessarily coincide with the polarization direction of the external fields used to drive the system.
