论文摘要
本文中的主要问题是信息如何从黑洞中泄漏出来。依靠代数论点和超选择扇区的概念,我们提出了某些操作员的存在,其相关性遍布黑洞大气层并范围范围为内部。这些黑洞互换包含在整个代数中,不属于描述半经典散装物理的亚代词。我们在操作员重建的背景下研究包含大量微晶格的代码空间。只要大气被排除在特定子系统之外,在相关代数的作用下看到的全局状态是最大混合的,因此由单个经典背景描述。一旦编码相关的相关性,即,如果代数足够扩大,则可以实现完美的状态可区分性。我们通过计算von Neumann熵来得出这一点,该熵可以解释通过将量子极端表面处方施加到混合状态而获得的结果。然后,我们在黑洞蒸发的背景下检查了这些见解,并认为信息通过黑洞互换转移到辐射。我们得出页面曲线。上面的机制表明,黑洞信息受拓扑保护。一个插入的观察者不会经历任何戏剧性。这可能会解决单位性问题而不遇到任何防火墙或州难题,后者在广义熵计算中很明显。我们还研究了如何理解某些虫洞拓扑结构的问题。我们认为它们在重力复制计算中的发生可能与旧黑洞周围的辐射与大气之间的最大相关性有关。这可能表明拓扑变化与近地平线量子重力效应之间存在联系。
The central question in this article is how information does leak out from black holes. Relying on algebraic arguments and the concept of superselection sectors, we propose the existence of certain operators whose correlations extend across the black hole atmosphere and range into the interior. Contained in the full algebra, these black hole intertwiners will not belong to the subalgebra describing semiclassical bulk physics. We study this proposal in the context of operator reconstructions for code spaces containing a large number of microstates. As long as the atmosphere is excluded from a particular subsystem, the global state seen under the action of the associated algebra is maximally mixed and therefore described by a single classical background. Once the relevant correlations are encoded, i.e. if the algebra is sufficiently enlarged, perfect state distinguishability becomes possible. We arrive at this by computing the von Neumann entropy which may explain the result obtained by applying the quantum extremal surface prescription to the mixed state. We then examine these insights in the context of black hole evaporation and argue that information is transferred to the radiation via black hole intertwiners. We derive the Page curve. The mechanism above suggests that black hole information is topologically protected. An infalling observer would experience no drama. This may resolve the unitarity problem without running into any firewall or state puzzle, the latter being evident in generalized entropy computations. We also examine the question of how certain wormhole topologies may be understood given these findings. We argue that their occurrence in gravity replica computations may be related to the maximal correlation between radiation and atmosphere surrounding the old black hole. This may suggest a connection between topology change and near horizon quantum gravitational effects.
