全息、CFT和黑洞熵

Holography, CFT and Black Hole Entropy

Parthasarathi Majumdar

摘要:

本文结合黑洞热力学讨论了引力物理中的全息或降维问题。生活在孤立视界上的自由度(作为宏观的、一般的、永恒的黑洞视界的模型)被认为是拓扑性质的,并利用它们与二维共形场论的关系进行计数。这导致了这些黑洞的微正则熵具有贝肯斯坦-霍金形式以及有限的、明确的{ \it量子时空}修正。辐射黑洞全息图的另一个方面是作为标准正则系综处理,孤立视界作为平均(平衡)配置。这是产生一个通用的标准热稳定性的一般辐射黑洞,作为一个下界的质量平衡孤立的地平线上的微正则熵。结合的饱和发生在分离热稳定相和不稳定相的相边界处,具有一阶相变的症状。

英文摘要:

Aspects of holography or dimensional reduction in gravitational physics are discussed with reference to black hole thermodynamics. Degrees of freedom living on Isolated Horizons (as a model for macroscopic, generic, eternal black hole horizons) are argued to be topological in nature and counted, using their relation to two dimensional conformal field theories. This leads to the microcanonical entropy of these black holes having the Bekenstein-Hawking form together with finite, unambigious {\it quantum spacetime} corrections. Another aspect of holography ensues for radiant black holes treated as a standard canonical ensemble with Isolated Horizons as the mean (equilibrium) configuration. This is shown to yield a universal criterion for thermal stability of generic radiant black holes, as a lower bound on the mass of the equilibrium isolated horizon in terms of its microcanonical entropy. Saturation of the bound occurs at a phase boundary separating thermally stable and unstable phases with symptoms of a first order phase transition.
