移动镜子被认为是模拟黑洞霍金辐射的易处理的装置。在本文中，关于黑洞信息问题的最新发展的动机，我们提出了广泛的研究共形场论中的运动镜采用场论以及全息方法。首先回顾了通常的场论公式的运动镜，我们构造其引力对偶诉诸AdS/BCFT建设。基于我们的全息公式，我们计算了各种运动镜模型中纠缠熵的时间演化。在这样做的过程中，我们主要关注三种不同的设置：逃逸镜，它模拟了从永恒黑洞发出的恒定霍金辐射;扭结镜，它模拟了由坍缩形成的蒸发黑洞;双逃逸镜，它模拟了两个不断辐射的永恒黑洞。特别是，通过计算全息纠缠熵，我们表明，扭结镜产生一个理想的佩奇曲线。我们还发现，一个有趣的相变的情况下出现的双逃逸镜。此外，我们认为，并提供证据的二维刘维尔引力的运动镜的解释。我们还讨论了运动镜模型中量子能量条件与全息纠缠熵时间演化的关系。
Moving mirrors have been known as tractable setups modeling Hawking radiation from black holes. In this paper, motivated by recent developments regarding the black hole information problem, we present extensive studies of moving mirrors in conformal field theories by employing both field theoretic as well as holographic methods. Reviewing first the usual field theoretic formulation of moving mirrors, we construct their gravity dual by resorting to the AdS/BCFT construction. Based on our holographic formulation, we then calculate the time evolution of entanglement entropy in various moving mirror models. In doing so, we mainly focus on three different setups: escaping mirror, which models constant Hawking radiation emanating from an eternal black hole; kink mirror, which models an evaporating black hole formed from collapse; and the double escaping mirror, which models two constantly radiating eternal black holes. In particular, by computing the holographic entanglement entropy, we show that the kink mirror gives rise to an ideal Page curve. We also find that an interesting phase transition arises in the case of the double escaping mirror. Furthermore, we argue and provide evidence for an interpretation of moving mirrors in terms of two dimensional Liouville gravity. We also discuss the connection between quantum energy conditions and the time evolution of holographic entanglement entropy in moving mirror models.
