摘要:

在渐近安全的背景下讨论了黑洞解的量子改进。在这个公式中的牛顿耦合依赖于一个能量尺度,它必须与一些长度尺度相一致,以便研究黑洞的物理后果。然而,迄今为止,还没有物理原理用于识别。在这里,我们提出,热力学热力学第一定律的一致性原则,应确定物理上合理的规模识别,至少接近地平线。我们表明,这导致一个自然的解决方案,牛顿耦合应该是一个函数的视界面积和找到一个普遍的公式的量子熵,这与标准的贝肯斯坦-霍金熵常数牛顿耦合,克尔黑洞和其他高维黑洞。这表明牛顿耦合是视界附近区域的函数,也是远离无穷远区域的函数,在无穷远区域,量子效应可能不那么重要。

英文摘要:

We discuss the quantum improvement of black hole solutions in the context of asymptotic safety. The Newton coupling in this formulation depends on an energy scale, which must be identified with some length scale in order to study physical consequences to black holes. However, no physical principle has so far been known for the identification. Here we propose that the consistency of the first law of thermodynamics is the principle that should determine physically sensible scale identification, at least close to the horizon. We show that this leads to a natural solution that the Newton coupling should be a function of the horizon area and find a universal formula for the quantum entropy, which agrees with the standard Bekenstein-Hawking entropy for constant Newton coupling, for Kerr black holes and other higher-dimensional black holes. This suggests that the Newton coupling is a function of the area near the horizon, and also away to infinity, where the quantum effects may not be so important.
