我们首次对三维(Banados-Teitelboim-Zanelli类型)一般黑洞的所有微态提出了明确的建议：黑洞微态，称为“视界绒毛”，是一类特殊的近视界软毛，其能量由视界观测者测量为零，并且在距离视界有限的距离内不能被观察者区分。这些态排列在与渐近黑洞几何有关的二维共形代数的轨道上。我们使用Hardy-Ramanujan公式对这些微态进行计数，该公式用于将给定整数划分为非负整数，从而恢复Bekenstein-Hawking熵。我们讨论了将我们的黑洞微态结构扩展到天体物理Kerr型黑洞的可能性。
We provide the first explicit proposal for all microstates of generic black holes in three dimensions (of Banados-Teitelboim-Zanelli type): black hole microstates, termed “horizon fluff,” are a particular class of near horizon soft hairs which have zero energy as measured by the horizon observer and cannot be distinguished by observers at a finite distance from the horizon. These states are arranged in orbits of the two-dimensional conformal algebra associated with the asymptotic black hole geometry. We count these microstates using the Hardy-Ramanujan formula for the number of partitions of a given integer into non-negative integers, recovering the Bekenstein-Hawking entropy. We discuss possible extensions of our black hole microstate construction to astrophysical Kerr-type black holes.
