黑洞、AdS和CFTs

Black Holes, AdS, and CFTs

Donald Marolf

摘要:

这个简短的会议论文集试图用相对论和其他非弦理论家可以理解的语言来解释反德西特/共形场论(AdS/CFT)对应对黑洞熵的意义。主要结论是,贝肯斯坦-霍金熵S_{BH}是与某些超选择扇区相关的状态密度,由所谓的边界观测量代数定义。有趣的是,虽然有一个有效的上下文可以将这个结果重新表述为“S_{BH}计算黑洞内部的所有状态”,但也可能有另一个上下文可以将其重新表述为“$S_{BH}$不计算黑洞内部的所有状态,而只计算那些与外部可区分的状态。“这些论点和结论代表了作者对社区集体智慧的翻译,并结合了一些最近的结果。关于WE-Heraeus研讨会:量子引力:挑战与展望,谨以此文纪念约翰·A。维勒

英文摘要:

This brief conference proceeding attempts to explain the implications of the anti-de Sitter/conformal field theory (AdS/CFT) correspondence for black hole entropy in a language accessible to relativists and other non-string theorists. The main conclusion is that the Bekenstein-Hawking entropy S_{BH} is the density of states associated with certain superselections sectors, defined by what may be called the algebra of boundary observables. Interestingly, while there is a valid context in which this result can be restated as "S_{BH} counts all states inside the black hole," there may also be another in which it may be restated as "$S_{BH}$ does not count all states inside the black hole, but only those that are distinguishable from the outside." The arguments and conclusions represent the author's translation of the community's collective wisdom, combined with a few recent results. For the proceedings of the WE-Heraeus-Seminar: Quantum Gravity: Challenges and Perspectives, dedicated to the memory of John A. Wheeler.
