论文摘要
我们系统地研究了二维形成共形场理论(CFT)中的运动镜模型。通过专注于他们的延迟行为,我们将镜像概要文件分为四个类,称为A类(时速)镜像,类型B(逃脱)镜子,类型C(追逐)镜子和类型D(终止)镜子。我们通过分析探索每种类型的能量通量和纠缠熵的特征,并确定其物理解释。此外,我们构建了他们的重力双重二元组,为世界末日(EOW)麸皮起着至关重要的作用。根据镜像类型,EOW Branes的轮廓显示出不同的行为。此外,我们还提供了一个标准,该标准可以决定CFTS中的复制方法是计算移动镜模型中的纠缠熵还是伪熵。
We systematically study moving mirror models in two-dimensional conformal field theory (CFT). By focusing on their late-time behavior, we separate the mirror profiles into four classes, named type A (timelike) mirrors, type B (escaping) mirrors, type C (chasing) mirrors, and type D (terminated) mirrors. We analytically explore the characteristic features of the energy flux and entanglement entropy for each type and work out their physical interpretation. Moreover, we construct their gravity duals for which end-of-the-world (EOW) branes play a crucial role. Depending on the mirror type, the profiles of the EOW branes show distinct behaviors. In addition, we also provide a criterion that decides whether the replica method in CFTs computes entanglement entropy or pseudo entropy in moving mirror models.
