AI 中文摘要
在这项工作中，我们研究了移动镜产生的模拟霍金辐射的量子纠缠特性。通过在量子场上定义窗口函数的两个探测器模式，我们量化了这些模式之间建立的二分纠缠。我们的结果表明，当镜子遵循具有非单调、随时间变化的加速度的轨迹时，探测器可获得的纠缠量会增加，同时伴随着负能量通量的发射。这表明负能量通量充当了信息可以返回的通道。为了证实这一观点，我们研究了相关伙伴模式的恢复或重建与镜子发射的负能量通量之间的关系。
英文摘要
In this work, we investigate the quantum entanglement properties of analog Hawking radiation produced by a moving mirror. Using two detector modes defined through window functions on a quantum field, we quantify the bipartite entanglement established between these modes. Our results reveal that the amount of entanglement accessible to the detectors increases when the mirror follows trajectories with non-monotonic, time-dependent acceleration, which are accompanied by the emission of negative energy flux. This indicates that the negative energy flux acts as a channel through which information can be returned. To substantiate this perspective, we examine how the recovery or reconstruction of the associated partner modes is related to the negative energy flux emitted by the mirror.
