论文摘要
我们在Minkowski时空中为黑洞构建了一个无限的微晶体家族，该家族具有有效的半经典描述，这些描述在黑洞内部崩溃的灰尘壳方面具有有效的半经典描述。量子机械虫洞会导致这些状态具有指数较小但通用的重叠。我们表明，这些重叠表明，微晶格跨越了对数尺寸的希尔伯特空间，等于事件范围的面积除以牛顿常数的四倍，这解释了Bekenstein-Hawking熵的统计来源。
We construct an infinite family of microstates for black holes in Minkowski spacetime which have effective semiclassical descriptions in terms of collapsing dust shells in the black hole interior. Quantum mechanical wormholes cause these states to have exponentially small, but universal, overlaps. We show that these overlaps imply that the microstates span a Hilbert space of log dimension equal to the event horizon area divided by four times the Newton constant, explaining the statistical origin of the Bekenstein-Hawking entropy.
