弦理论中的黑洞内部

On the black hole interior in string theoy

Roy Ben-Israel, Amit Giveon, Nissan Itzhaki, Lior Liram

摘要:

在经典理论中,永恒黑洞视界背后的势能是用外部观测者可以获得的数据来描述的--波在黑洞上散射的反射系数。在广义相对论和微扰弦论中(在$α'$中),势在视界处是正则的,在奇点处爆炸。$SL(2,\mathbb{R})_k/U(1)$黑洞的精确反射系数,包括非微扰的$α'$效应,似乎暗示着视界后面有一个高度非平凡的结构。

英文摘要:

The potential behind the horizon of an eternal black hole in classical theories is described in terms of data that is available to an external observer -- the reflection coefficient of a wave that scatters on the black hole. In GR and perturbative string theory (in $α'$), the potential is regular at the horizon and it blows up at the singularity. The exact reflection coefficient, that is known for the $SL(2,\mathbb{R})_k/U(1)$ black hole and includes non-perturbative $α'$ effects, seems however to imply that there is a highly non-trivial structure just behind the horizon.
