论文摘要
我们表明，在任何维度上，轴对称杀伤层的近摩区域的重力相空间都承认一个2D形式的形式对称代数，其中央电荷与该区域成比例。这扩展了[Haco等。 Al。，JHEP 12，098（2018）]，用于在爱因斯坦方程解决方案中出现的通用杀戮视野，并从2D形式的结构域理论来激励全息描述。这样的田间理论中的基本熵与地平线的Bekenstein-Hawking熵一致，这表明了微观的解释。
We show that the gravitational phase space for the near-horizon region of a bifurcate, axisymmetric Killing horizon in any dimension admits a 2D conformal symmetry algebra with central charges proportional to the area. This extends the construction of [Haco et. al., JHEP 12, 098 (2018)] to generic Killing horizons appearing in solutions of Einstein's equations, and motivates a holographic description in terms of a 2D conformal field theory. The Cardy entropy in such a field theory agrees with the Bekenstein-Hawking entropy of the horizon, suggesting a microscopic interpretation.
