摘要

为了寻找量子引力中坍缩物体的新解,我们在本文中考虑了一个康托斯基-萨克斯(Kantowski-Sachs)度量,该度量由没有经典意义的参数标注。此外,我们还加入了一个克莱因-戈登场(Klein-Gordon field),以简单的方式表示渗透时空的不可避免的零点真空波动。在这个框架下,我们对系统进行量子化,得到惠勒-德威特方程,从而关注内部的深量子机制,并分析黑洞可能经历的各种转变。惠勒-德威特方程揭示了除了量子黑洞之外,还存在不同性质的新解,本文称之为 "量子灰洞",所有解都满足德威特边界条件。新解的存在带来了量子黑洞向量子灰洞过渡的新可能性。我们发现存在量子黑洞向量子灰洞过渡的非零概率。这些过渡概率在系统特征值的连续范围内表现出共振。

Black hole to grey hole metamorphosis in the deep quantum regime

In order to search for new solutions for collapsed objects in quantum gravity, we consider in this paper a Kantowski–Sachs metric labelled by parameters that have no classical significance. In addition, we include a Klein–Gordon field to represent in a simple manner the inevitable zero-point vacuum fluctuations that permeate the spacetime. With this framework, we quantize the system and obtain the Wheeler–DeWitt equation in order to focus upon the deep quantum regime of the interior and to analyze any kind of transition that the black hole may undergo. The Wheeler–DeWitt equation reveals the existence of new solutions of different nature, designated herein as “quantum grey holes,” in addition to the existence of quantum black holes, with all solutions satisfying the DeWitt boundary condition. The existence of new solutions gives rise to the novel possibility of a quantum black hole making a transition to a quantum grey hole. We find that there exists non-zero probability of quantum black-to-grey hole transition. These transition probabilities exhibit resonances for a continuous range of eigenvalues of the system.
