关于AdS3引力的量子化Ⅰ:半经典分析

On Quantization of AdS3 Gravity I: Semi-Classical Analysis

M. M. Sheikh-Jabbari, Hossein Yavartanoo

摘要:

在这项工作中,我们探讨了量子化AdS $_3$爱因斯坦引力的想法。我们从最一般的解决方案,尊重布朗-亨诺边界条件的三维引力理论。这些解由两个全纯函数表示,并满足简单叠加法则。这些几何一般都有一个分叉的Killing视界(具有非紧分叉曲线),它不是事件视界,因此也不是黑洞。尽管如此,仍存在具有事件视界的这些几何的叠加。我们建议把这些几何形状看作是BTZ黑洞的“半经典模糊球微观态”,它们是这些几何形状的叠加。这些半经典微观态的量子化的细节将在接下来的工作中讨论。

英文摘要:

In this work we explore ideas in quantizing AdS$_3$ Einstein gravity. We start with the most general solution to the 3d gravity theory which respects Brown-Henneaux boundary conditions. These solutions are specified by two holomorphic functions and satisfy simple superposition rule. These geometries generically have a bifurcate Killing horizon (with a noncompact bifurcation curve) which is not an event horizon and are hence not black holes. Nonetheless, there are superpositions of these geometries which have event horizon. We propose to view these geometries as "semiclassical fuzzball microstates" of BTZ black holes appearing as superposition of these geometries. The details of quantization of these semiclassical microstates will be discussed in an upcoming work.
