The exact formula derived by us earlier for the entropy of a four dimensional nonrotating black hole within the quantum geometry formulation of the event horizon in terms of boundary states of a three dimensional Chern-Simons theory is reexamined for large horizon areas. In addition to the semiclassical Bekenstein-Hawking contribution proportional to the area obtained earlier, we find a contribution proportional to the logarithm of the area together with subleading corrections that constitute a series in inverse powers of the area.
我们之前在事件视界的量子几何公式中，根据三维陈 - 西蒙斯理论的边界态推导出的四维非旋转黑洞熵的精确公式，针对大视界面积进行了重新审视。除了之前得到的与面积成正比的半经典贝肯斯坦 - 霍金贡献外，我们还发现了一个与面积的对数成正比的贡献，以及构成面积倒数幂级数的次主导修正。
