旋转黑洞的经典内部结构与静态黑洞有很大的不同。我们考虑旋转的Banados-Teitelboim-Zanelli黑洞，并从规范理论探测它们的内部。利用简单的几何和逆向工程的测地线，我们提出了一个热相关器的建设，可以解释为产生于两个纠缠共形场理论。通过解析延拓这些算子，我们可以探测柯西视界。在我们的工作中，捕获柯西视界的相关器的结构与捕获非旋转Banados-Teitelboim-Zanelli奇点的相关器的结构密切相关。正如预期的那样，柯西视界以外的区域在这幅图中没有被探测到，保护了宇宙审查。
The classical internal structure of spinning black holes is vastly different from that of static black holes. We consider spinning Banados-Teitelboim-Zanelli black holes, and probe their interior from the gauge theory. Utilizing the simplicity of the geometry and reverse engineering from the geodesics, we propose a thermal correlator construction which can be interpreted as arising from two entangled conformal field theories. By analytic continuation of these correlators, we can probe the Cauchy horizon. Correlators that capture the Cauchy horizon in our work have a structure closely related to those that capture the singularity in a nonrotating Banados-Teitelboim-Zanelli. As expected, the regions beyond the Cauchy horizon are not probed in this picture, protecting cosmic censorship.
