摘要

我们计算了Karch-Randall膜世界中量子BTZ黑洞的全息类时纠缠熵。这些黑洞是膜上大质量三维引力的精确解，并且被推测为二维缺陷CFTs的热态对偶，存在于膜的界面和体AdS4的边界。我们的分析揭示了tEE和与对偶CFT相关的中心电荷之间的有趣关系，该对偶CFT由于Karch-Randall膜上的量子反反应效应而接受了非琐琐的修正，这是非摄动的。

Timelike entanglement and central charge for quantum BTZ black holes

We compute holographic timelike entanglement entropy for quantum BTZ black holes in a Karch-Randall braneworld scenario. These black holes are exact solutions of massive 3d gravity on the brane and are conjectured to be dual to thermal states in 2d defect CFTs, living at the interface of the brane and the boundary of the bulk

A d S_{4}

. Our analysis reveals an interesting relation between the tEE and the central charge pertaining to the dual CFT, which receives nontrivial corrections due to quantum backreaction effects on the Karch-Randall brane, which is explored non-perturbatively.
