AI总结:

本文在改进动力学方法框架下研究黑洞视界附近的量子几何效应,发现强量子效应使黑白洞视界消失并被无限个过渡面取代,从而使KS时空测地完备且不存在黑白洞结构。

摘要:

本文在改进动力学方法的框架内,研究了Einstein经典理论中经典黑洞视界曾出现位置附近的量子几何效应,其中黑洞内部区域由Kantowski-Sachs(KS)时空建模,且两个polymerization参数为相空间变量的函数。详细分析表明,这些效应极其强烈,以至于有效量子理论中的黑洞与白洞视界根本不存在,而是被过渡面所取代。在这些过渡面上,度规系数及其逆均光滑且保持有限,相应的曲率(包括Kretschmann标量)也是如此。这些过渡面始终将捕获区与反捕获区分隔开来。此类过渡面的数量是无限的,因此相应的KS时空成为测地完备的,且在该方案中不存在任何类似黑洞与白洞的结构。

英文摘要:

In this paper, we study the quantum geometric effects near the locations where classical black hole horizons used to appear in Einstein's classical theory, within the framework of an improved dynamic approach, in which the internal region of a black hole is modeled by the Kantowski-Sachs (KS) spacetime and the two polymerization parameters are functions of the phase space variables. Our detailed analysis shows that the effects are so strong that black and white hole horizons of the effective quantum theory do not exist at all and instead are replaced by transition surfaces, across which the metric coefficients and their inverses are smooth and remain finite, as are the corresponding curvatures, including the Kretschmann scalar. These surfaces always separate trapped regions from anti-trapped regions. The number of such surfaces is infinite, so the corresponding KS spacetimes become geodesically complete, and no black and white hole-like structures exist in this scheme.
