We study the entanglement dynamics between two cavities when one them is harmonically shaken in the context of relativistic quantum information. We find four different regimes depending on the frequency of the motion and the spectrum of the moving cavity. If the moving cavity is three dimensional only two modes inside get coupled and the entanglement can either degrade asymptotically with time or oscillate depending on the driving. On the other hand, if the cavity has an equidistant spectrum the entanglement can either vanish asymptotically if it is driven with its fundamental frequency or have a sudden death if it is driven with an uneven harmonic frequency.

由于动态卡西米尔效应导致的腔模纠缠退化

我们研究了在相对论量子信息的背景下，当两个腔中的一个被谐波振动时，两个腔之间的纠缠动力学。根据运动频率和移动腔的频谱，我们发现了四种不同的状态。如果移动腔是三维的，则内部只有两种模式会耦合，并且纠缠可以随时间渐近地退化或根据驱动而振荡。另一方面，如果腔具有等距频谱，则纠缠可以在以基频驱动时渐近消失，或者在以不均匀谐波频率驱动时突然消失。
