摘要

利用开放量子系统理论研究了加速原子的纠缠动力学。我们考虑两个原子沿着具有不同固有时的不同双曲轨迹运动。利用广义主方程讨论了一对偶极子与电磁场相互作用的动力学问题。讨论了适当的加速度在纠缠收获和猝死现象中所起的基本作用。最后，我们讨论了原子的极化如何影响我们的结果。对于某些偏振构型的选择，我们不再观察到纠缠收获现象。

A dynamic theory of entanglement for uniformly accelerated atoms

We study the entanglement dynamics of accelerated atoms using the theory of open quantum systems. We consider two atoms traveling along different hyperbolic trajectories with different proper times. We use the generalized master equation to discuss the dynamics of a pair of dipoles interacting with the electromagnetic field. The fundamental role played by proper acceleration in the entanglement harvesting and sudden death phenomenon is discussed. Finally, we discuss how the polarization of the atoms affects our results. For some choices of the polarization’s configuration, we no longer observe the entanglement harvesting phenomenon.
