AdS/CFT中的局部体算子与BTZ奇异性的命运

Local bulk operators in AdS/CFT and the fate of the BTZ singularity

Alex Hamilton, Daniel Kabat, Gilad Lifschytz, David A. Lowe

摘要:

本文分为两部分.首先,我们回顾了Lorentzian AdS中的局部体算符在边界CFT中的非局部算符的描述。我们讨论了在纯AdS背景下体局域性是如何产生的以及在有限N下体局域性是如何改变的。接下来我们给出了关于BTZ黑洞的一些新结果:局域算符可以定义在有限N个BTZ黑洞的视界内,这表明BTZ几何描述了黑洞微观态的平均,但具有有限N效应来解决奇点。

英文摘要:

This paper has two parts. First we review the description of local bulk operators in Lorentzian AdS in terms of non-local operators in the boundary CFT. We discuss how bulk locality arises in pure AdS backgrounds and how it is modified at finite N. Next we present some new results on BTZ black holes: local operators can be defined inside the horizon of a finite N BTZ black hole, in a way that suggests the BTZ geometry describes an average over black hole microstates, but with finite N effects resolving the singularity.
