We review recent developments in Jackiw–Teitelboim gravity. This is a simple solvable model of quantum gravity in two dimensions (that arises e.g. from the s-wave sector of higher dimensional gravity systems with spherical symmetry). Due to its solvability, it has proven to be a fruitful toy model to analyze important questions such as the relation between black holes and chaos, the role of wormholes in black hole physics and holography, and the way in which information that falls into a black hole can be recovered.

量子黑洞的可解模型：Jackiw-Teitelboim 引力综述

我们回顾了 Jackiw-Teitelboim 引力的最新发展。这是二维量子引力的简单可解模型（例如，源自具有球对称性的高维引力系统的 s 波扇区）。由于其可解性，它已被证明是一个富有成效的玩具模型，可以分析黑洞与混沌之间的关系、虫洞在黑洞物理和全息术中的作用以及信息落入黑洞的方式等重要问题。洞可以恢复。
