全息、规范引力联系与黑洞熵

Holography, Gauge-Gravity Connection and Black Hole Entropy

Parthasarathi Majumdar

摘要:

全息的问题和可能的联系与时空物理学中的规范理论进行了讨论,在一个方法相当不同的更受限制的AdS-CFT对应。在黑洞热力学的背景下,全息术的一个特殊概念是从相当基本的考虑导出的(而不是被证明的),这也导致了辐射黑洞的热稳定性的判据,而不诉诸于特定的经典度规。对于遵守这个准则的黑洞,正则熵可以用孤立视界的微正则熵来表示,孤立视界本质上是全局事件视界的局部推广,是空的时空内边界,具有边际外捕获。有人认为,为什么在这个地平线上的自由度必须描述的拓扑规范理论。量子化这一边界理论导致视界的微正则熵以横截面积的无穷级数渐近表示,其中领先的“面积定律”项后面是由量子时空涨落引起的有限的、明确可计算的修正。

英文摘要:

The issues of holography and possible links with gauge theories in spacetime physics is discussed, in an approach quite distinct from the more restricted AdS-CFT correspondence. A particular notion of holography in the context of black hole thermodynamics is derived (rather than conjectured) from rather elementary considerations, which also leads to a criterion of thermal stability of radiant black holes, without resorting to specific classical metrics. For black holes that obey this criterion, the canonical entropy is expressed in terms of the microcanonical entropy of an Isolated Horizon which is essentially a local generalization of the very global event horizon and is a null inner boundary of spacetime, with marginal outer trapping. It is argued why degrees of freedom on this horizon must be described by a topological gauge theory. Quantizing this boundary theory leads to the microcanonical entropy of the horizon expressed in terms of an infinite series asymptotic in the cross-sectional area, with the leading `area-law' term followed by finite, unambiguously calculable corrections arising from quantum spacetime fluctuations.
