晚期黑洞内部的体积

The volume of the black hole interior at late times

Luca V. Iliesiu, Márk Mezei, Gábor Sárosi

摘要:

了解半经典黑洞解在非常晚的时间的命运是量子引力中最重要的开放问题之一。在本文中,我们提供了一个路径积分的体积的黑洞内部的定义和研究它在任意晚的时间在各种模型的二维引力黑洞。由于半经典黑洞谱的贡献和它的一些非微扰修正之间的一种新的普遍抵消,我们发现,在早期的线性增长之后,内部的长度在一个时间饱和,并且朝向一个值,该值在黑洞的熵中呈指数级大。这提供了复杂度等于体积提议的非微扰确认,因为复杂度也预期在相同值和同时达到稳定。

英文摘要:

Understanding the fate of semi-classical black hole solutions at very late times is one of the most important open questions in quantum gravity. In this paper, we provide a path integral definition of the volume of the black hole interior and study it at arbitrarily late times for black holes in various models of two-dimensional gravity. Because of a novel universal cancellation between the contributions of the semi-classical black hole spectrum and some of its non-perturbative corrections, we find that, after a linear growth at early times, the length of the interior saturates at a time, and towards a value, that is exponentially large in the entropy of the black hole. This provides a non-perturbative confirmation of the complexity equals volume proposal since complexity is also expected to plateau at the same value and at the same time.
