Black Hole evaporation: A Perspective from Loop Quantum Gravity

论文摘要
对黑洞蒸发过程的个人观点是使用：（i）循环量子重力，（ii）获得混凝土结果的简化模型，以及（iii）半古典量子量子相对论的简化模型。一方面，最终图片是保守的，因为有具体的结果支持了争论的每个阶段，并且在宏观黑洞以外的驯服区域中，与一般相对论或半古典引力没有很大的不同。另一方面，它反对在许多方面通常存在的某些观点，例如：构成时空最终边界的一部分的奇异性的持久性； \ emph {event}地平线的存在是内部和外部之间的绝对屏障；并且（通常是隐式的）要求必须在代表此事件范围扩展的“最后一个光线”达到$ \ Mathcal {i}^{+} $时完成净化。
A personal perspective on the black hole evaporation process is presented using as guidelines inputs from: (i) loop quantum gravity, (ii) simplified models where concrete results have been obtained, and, (iii) semi-classical quantum general relativity. On the one hand, the final picture is conservative in that there are concrete results that support each stage of the argument, and there are no large departures from general relativity or semi-classical gravity in tame regions outside macroscopic black holes. On the other hand it argues against certain views that are commonly held in many quarters, such as: persistence of a piece of singularity that constitutes a part of the final boundary of space-time; presence of an \emph{event} horizon serving as an absolute barrier between the interior and the exterior; and the (often implicit) requirement that purification must be completed by the time the `last rays' representing the extension of this event horizon reach $\mathcal{I}^{+}$.
