利用圈量子引力方法对Schwarzschild黑洞内部进行量子化。在模型中求解了哈密顿约束,得到了物理希尔伯特空间。用解析和数值方法研究了Schwarzschild黑洞ADM质量对应的Dirac可观测量的性质。结果是零不在狄拉克可观测的光谱中。这支持了黑洞蒸发后存在稳定的残余物。我们的结论是有效的环路量化的模型所采用的一般类的计划。
The interior of Schwarzschild black hole is quantized by the method of loop quantum gravity. The Hamiltonian constraint is solved and the physical Hilbert space is obtained in the model. The properties of a Dirac observable corresponding to the ADM mass of the Schwarzschild black hole are studied by both analytical and numerical techniques. It turns out that zero is not in the spectrum of this Dirac observable. This supports the existence of a stable remnant after the evaporation of a black hole. Our conclusion is valid for a general class of schemes adopted for loop quantization of the model.
