论文摘要
我们研究了极端超对称黑洞的重力描述。我们指出，$ ADS_2 $附近的地平线几何形状可用于计算有趣的可观察物，例如操作员的相关功能。在此极限下，哈密顿量为零，相关函数是独立的。我们讨论了黑洞微晶体的重力描述的一些可能影响。我们还与SYK的超对称版本中的数值结果进行了比较。这些结果也可以解释为提供了连接两个极端黑洞的虫洞的结构。这是更长，更具技术性的伴侣论文ARXIV的简短版本：2207.00408。
We study the gravitational description of extremal supersymmetric black holes. We point out that the $AdS_2$ near horizon geometry can be used to compute interesting observables, such as correlation functions of operators. In this limit, the Hamiltonian is zero and correlation functions are time independent. We discuss some possible implications for the gravity description of black hole microstates. We also compare with numerical results in a supersymmetric version of SYK. These results can also be interpreted as providing a construction of wormholes joining two extremal black holes. This is the short version of a longer and more technical companion paper arXiv:2207.00408.
