全息纠缠平台

Holographic entanglement plateaux

Veronika E. Hubeny, Henry Maxfield, Mukund Rangamani, Erik Tonni

摘要:

本文研究了有限体积全息场论的纠缠熵。我们发现,Araki-Lieb不等式是饱和的足够大的子区域,这意味着热熵可以恢复的区域和它的补充的知识。我们观察到,由于与给定边界区域相关的因果楔形的非平凡特征,这实际上是在全息设置中强加给我们的。在这个过程中,我们提出了一个无限集的极值曲面Schwarzschild-AdS几何锚定在一个给定的纠缠表面。我们还提供了一些关于计算全息纠缠熵所需的同调约束的推测。

英文摘要:

We consider the entanglement entropy for holographic field theories in finite volume. We show that the Araki-Lieb inequality is saturated for large enough subregions, implying that the thermal entropy can be recovered from the knowledge of the region and its complement. We observe that this actually is forced upon us in holographic settings due to non-trivial features of the causal wedges associated with a given boundary region. In the process, we present an infinite set of extremal surfaces in Schwarzschild-AdS geometry anchored on a given entangling surface. We also offer some speculations regarding the homology constraint required for computing holographic entanglement entropy.
