Naively, resolving the black hole information paradox requires microscopic details about quantum gravity. Recent work suggests that, instead, a unitary Page curve can be recovered by adding disorder-averaged replica instantons to the path integral, though their origin is unclear. In this Letter, we show how replica instantons and disorder averaging emerge naturally in an effective theory built from typical microscopic states. We relate replica instantons to a moment expansion of simple operators, and find a microcanonical description in terms of wormholes and Euclidean black holes.

本征态热化和重力平均失调。

天真的,解决黑洞信息悖论需要有关量子引力的微观细节。最近的工作表明,可以通过将平均无序的副本实例添加到路径积分中来恢复单一的Page曲线,尽管其起源尚不清楚。在这封信中,我们展示了如何在典型的微观状态基础上建立的有效理论中自然而然地产生复制实例和无序平均。我们将复制实例与简单算子的矩展开联系起来,并根据虫洞和欧几里得黑洞找到了微规范描述。
