视界上的刘维理论:走向黑洞的量子理论

Liouville Theory on Horizons: Towards a Quantum Theory of Black Holes

Edi Halyo

摘要:

我们表明,任何非极值黑洞可以描述的刘维尔理论,生活在其非常近的视界区域。在经典的刘维尔理论中,黑洞对应于一个再现林德勒度规的场结构。在量子刘维尔理论中,CFT中的黑洞态是由穿刺算子产生的,穿刺算子产生了亏损角为$2 π$的圆锥奇点。这种状态是“重”的,在小超空间近似下具有不可归一化的波函数。黑洞熵计算了通过与CFT中的“光、量子”算子的乘积作用而获得“重”黑洞状态的方式的数量。黑洞毛在CFT中被称为“背景电荷”,但其物理性质尚不清楚。

英文摘要:

We show that any nonextremal black hole can be described by a Liouville theory that lives on its very near horizon region. In classical Liouville theory, the black hole corresponds to a field configuration that reproduces the Rindler metric. In quantum Liouville theory, the black hole state in the CFT is created by the puncture operator that gives rise to a conical singularity with a deficit angle of $2 π$. This state is "heavy" with a nonnormalizable wave function in the minisuperspace approximation. Black hole entropy counts the number of ways the "heavy" black hole state can be obtained by acting with a product of "light, quantum" operators in the CFT. Black hole hair is described by the "background charge" in the CFT but its physical nature is unclear.
