论文摘要
通过考虑Loop量子宇宙学中的量子Oppenheimer-Snyder模型,这是一种新的量子黑洞模型,其度量张量是一种适当变形的Schwarzschild。量子效应暗示着塌陷的尘埃球产生的黑洞的质量。对于事件范围确实形成的较大质量的情况,研究了时空及其性质的最大延伸。通过讨论与Quantum oppenheimer-snyder相反的情况,可以通过量子宇宙包围的气泡获得量子瑞士奶酪模型。该模型类似于Black Hole宇宙学或Fecund Univers,其中大爆炸与白洞有关。因此,我们的模型为宇宙学现象学打开了一个新的窗口。
By considering the quantum Oppenheimer-Snyder model in loop quantum cosmology, a new quantum black hole model whose metric tensor is a suitably deformed Schwarzschild one is derived. The quantum effects imply a lower bound on the mass of the black hole produced by the collapsing dust ball. For the case of larger masses where the event horizon does form, the maximal extension of the spacetime and its properties are investigated. By discussing the opposite scenario to the quantum Oppenheimer-Snyder, a quantum Swiss Cheese model is obtained with a bubble surrounded by the quantum universe. This model is analogous to black hole cosmology or fecund universes where the big bang is related to a white hole. Thus our models open a new window to cosmological phenomenology.
