Abstract

For a system with a Hamiltonian constraint, we demonstrate that its dynamics is invariant under different choices of the lapse function, regardless of whether the Hamiltonian incorporates quantum corrections. Applying this observation to the interior of black-to-white holes, we analyze its dynamics with different choices of the lapse function. The results explicitly show that the leading-order expansion of both metrics proposed by Rovelli et al. (Class. Quant. Grav. 35, 225003 (2018); Class. Quant. Grav. 35, 215010 (2018)) and Ashtekar et al. (Phys. Rev. Lett. 121, 241301 (2018); Phys. Rev. D 98, 126003 (2018)) exhibit identical behavior near the transition surface. Therefore, in this sense the black-to-white hole model proposed by Rovelli et al., (Class. Quant. Grav. 35, 225003 (2018); Class. Quant. Grav. 35, 215010 (2018)) may be interpreted as a coarse-grained version of the solution within the framework of loop quantum gravity. The black-to-white hole solutions with exact symmetry between the black hole and white hole regions are constructed by appropriately fixing the quantum parameters in the effective theory of loop quantum gravity. This approach circumvents the issue of amplification of mass, which could arise from a mass difference between the black hole and white hole, and provides a way to link the solutions obtained by minisuperspace quantization to those in the covariant approach. Finally, the black-to-white hole solutions with a cosmological constant are constructed. The numerical solutions for the interior of the black-to-white hole with a cosmological constant are obtained, and their symmetric behavior is also discussed.

具有宇宙常数的对称黑-白洞解
对于具有哈密顿约束的系统,无论哈密顿约束是否包含量子修正,在不同的失效函数选择下,其动力学都是不变的。将这一观测结果应用于黑白洞内部,分析了不同延时函数选择下的动态特性。结果明确地表明,Rovelli et al. (Class.)提出的两个度量的导阶展开式。数理学报,35,225003 (2018);类。量子力学。35,215010(2018))和Ashtekar等人。Rev. Lett. 121,241301 (2018);理论物理。Rev. D 98, 126003(2018))在过渡表面附近表现出相同的行为。因此,从这个意义上说,Rovelli等人提出的黑-白洞模型,(Class。数理学报,35,225003 (2018);类。Quant. gravity. 35, 215010(2018))可以被解释为环量子引力框架内解决方案的粗粒度版本。通过适当固定圈量子引力有效理论中的量子参数,构造了黑洞和白洞区域之间具有精确对称性的黑-白洞解。这种方法避免了黑洞和白洞之间的质量差可能引起的质量放大问题,并提供了一种将由超空间量子化得到的解与协变方法得到的解联系起来的方法。最后,构造了具有宇宙常数的黑-白洞解。得到了具有宇宙常数的黑白洞内部的数值解,并讨论了它们的对称性质。
