Abstract

We present a first-principles derivation of the main results of the Kerr/CFT correspondence and its extensions using only tools from gravity and quantum field theory, filling a few gaps in the literature when necessary. Firstly, we review properties of extremal black holes that imply, according to semi-classical quantization rules, that their near-horizon quantum states form a centrally-extended representation of the one-dimensional conformal group. This motivates the conjecture that the extremal Kerr and Reissner-Nordstr?m black holes are dual to the chiral limit of a two-dimensional CFT. We also motivate the existence of an SL(2, ?) family of two-dimensional CFTs, which describe in their chiral limit the extremal Kerr-Newman black hole. We present generalizations in anti-de Sitter spacetime and discuss other matter-coupling and higher-derivative corrections. Secondly, we show how a near-chiral limit of these CFTs reproduces the dynamics of near-superradiant probes around near-extremal black holes in the semi-classical limit. Thirdly, we review how the hidden conformal symmetries of asymptotically-flat black holes away from extremality, combined with their properties at extremality, allow for a microscopic accounting of the entropy of non-extremal asymptotically-flat rotating or charged black holes. We conclude with a list of open problems.

Kerr/CFT对应及其扩展
我们提出了Kerr/CFT对应及其扩展的主要结果的第一原理推导,仅使用重力和量子场论的工具,在必要时填补了文献中的一些空白。首先,我们回顾了极端黑洞的性质,根据半经典量子化规则,它们的近视界量子态形成了一维共形群的中心扩展表示。这激发了人们的猜想:克尔和瑞斯纳-诺德斯特?m个黑洞对偶于二维CFT的手性极限。我们还激发了二维cft的SL(2, ?)族的存在,它们描述了极端Kerr-Newman黑洞的手性极限。我们给出了在反德西特时空中的推广,并讨论了其他物质耦合和高导数修正。其次,我们展示了这些cft的近手性极限是如何在半经典极限下再现近极黑洞周围近超辐射探测器的动力学的。第三,我们回顾了渐近平坦黑洞在远离极值处的隐藏共形对称性,结合它们在极值处的性质,如何允许对非极值渐近平坦旋转或带电黑洞的熵进行微观计算。最后,我们列出了一系列尚未解决的问题。

期刊介绍: Living Reviews in Relativity is a peer-reviewed, platinum open-access journal that publishes reviews of research across all areas of relativity. Directed towards the scientific community at or above the graduate-student level, articles are solicited from leading authorities and provide critical assessments of current research. They offer annotated insights into key literature and describe available resources, maintaining an up-to-date suite of high-quality reviews, thus embodying the "living" aspect of the journal's title. Serving as a valuable tool for the scientific community, Living Reviews in Relativity is often the first stop for researchers seeking information on current work in relativity. Written by experts, the reviews cite, explain, and assess the most relevant resources in a given field, evaluating existing work and suggesting areas for further research. Attracting readers from the entire relativity community, the journal is useful for graduate students conducting literature surveys, researchers seeking the latest results in unfamiliar fields, and lecturers in need of information and visual materials for presentations at all levels.
