论文摘要
我们研究旋转对欧洲源(量子)黑洞的尘埃核心范围光谱的影响。物理。 J. C 82(2022)10。假定尘埃球以足够慢的角速度稳定地旋转,可以应用扰动理论。像总质量一样,总角动量被证明是在普朗克单元中定量的,因此地平线也是如此。对于最外层的质量足够小的小部分,该模型接收基态,可以在扰动状态下快速旋转,以描述常规旋转物体而不是黑洞。
We study the effect of rotation on the spectrum of bound states for dust cores that source (quantum) black holes found in Eur. Phys. J. C 82 (2022) 10. The dust ball is assumed to spin rigidly with sufficiently slow angular velocity that perturbation theory can be applied. Like the total mass, the total angular momentum is shown to be quantised in Planck units, hence so is the horizon area. For sufficiently small fraction of mass in the outermost layer, the model admits ground states which can spin fast enough within the perturbative regime so as to describe regular rotating objects rather than black holes.
