具有亚普朗克曲率的正则黑洞

Regular black holes with sub-Planckian curvature

Yi Ling, Meng-He Wu

AI总结:

本文基于含潮汐力效应的弯曲时空广义不确定原理,构造出具有亚普朗克Kretschmann曲率、指数抑制引力势和渐近闵可夫斯基核的正则黑洞,其大尺度下可重现Bardeen等黑洞度规。

摘要:

我们构造了一类Kretschmann标量曲率为亚普朗克的正则黑洞。这类正则黑洞的度规具有指数抑制的引力势和渐近闵可夫斯基核的特征。特别地,通过选择不同的势形式,它们在大尺度下可重现Bardeen/Hayward/Frolov黑洞的度规。基于弯曲时空的广义不确定原理(含潮汐力对有限大小物体的影响,物体大小下限为最小长度),我们对这类黑洞进行了启发式推导。

英文摘要:

We construct a sort of regular black holes with a sub-Planckian Kretschmann scalar curvature. The metric of this sort of regular black holes is characterized by an exponentially suppressing gravity potential as well as an asymptotically Minkowski core. In particular, with different choices of the potential form, they can reproduce the metric of Bardeen/Hayward/Frolov black hole at large scales. The heuristical derivation of this sort of black holes is performed based on the generalized uncertainty principle over curved spacetime which includes the effects of tidal force on any object with finite size which is bounded below by the minimal length.
