反射边界附近加速原子的Unruh效应和纠缠产生

The Unruh effect and entanglement generation for accelerated atoms near a reflecting boundary

Jialin Zhang, Hongwei Yu

摘要:

在开放系统的框架下,研究了两个独立的匀加速原子与无质量标量场真空涨落相互作用系统在反射平面边界上的纠缠产生.我们证明,与边界的存在下,加速原子表现出不同的功能,从静态的在相应的Unruh温度的热浴在初始时间附近的纠缠创建。在这个意义上,真空中加速的原子不一定表现得像在温鲁温度的热浴中静止一样。

英文摘要:

We study, in the framework of open systems, the entanglement generation of two independent uniformly accelerated atoms in interaction with the vacuum fluctuations of massless scalar fields subjected to a reflecting plane boundary. We demonstrate that, with the presence of the boundary, the accelerated atoms exhibit distinct features from static ones in a thermal bath at the corresponding Unruh temperature in terms of the entanglement creation at the neighborhood of the initial time. In this sense, accelerated atoms in vacuum do not necessarily have to behave as if they were static in a thermal bath at the Unruh temperature.
