The AdS/CFT correspondence has recently provided a novel approach for counting the microstates of black holes impressively matching the macroscopic Bekenstein–Hawking entropy formula of rotating electrically charged asymptotically AdS black holes in four to seven dimensions. This approach is designed for supersymmetric extremal black holes, but can also be extended to nonsupersymmetric, near-extremal black holes. Besides the dual higher-dimensional boundary CFT, an effective 2D CFT emerges in a certain near-horizon limit accounting for both the extremal and the near-extremal black hole entropies. This effective 2D description is universal across dimensions and comes naturally equipped with an approach to quantitatively tackle aspects of Hawking radiation.

从微观黑洞熵到霍金辐射c

AdS/CFT 对应关系最近提供了一种新的方法来计算黑洞的微观状态，这与宏观 Bekenstein-Hawking 熵公式在 4 到 7 维中旋转带电渐近 AdS 黑洞的结果非常吻合。这种方法是为超对称极值黑洞设计的，但也可以扩展到非超对称、近极值黑洞。除了双高维边界 CFT 外，有效的 2D CFT 出现在某个近视界极限中，同时考虑了极值和近极值黑洞熵。这种有效的二维描述在各个维度上都是通用的，并且自然配备了一种定量处理霍金辐射方面的方法。
