We present a modified Schwarzschild solution for a model of evaporation of a black hole with information preservation. By drawing a direct analogy to the quantum pure accelerating mirror (dynamical Casimir effect of a 1D horizon), we derive a Schwarzschild metric with not only the usual Schwarzschild radius but an additional length scale related to the Planck length. The black hole has thermal particle production that leads to complete evaporation of the black hole, resulting in non-divergent entanglement entropy, Page curve turn-over, and an asymptotic quantum pure state with no information loss.

来自单一加速镜模拟的修正 Schwarzschild 度量

我们提出了一个改进的 Schwarzschild 解，用于具有信息保存的黑洞蒸发模型。通过对量子纯加速镜（一维视界的动态卡西米尔效应）进行直接类比，我们推导出一个施瓦西度量，不仅具有通常的施瓦西半径，而且还具有与普朗克长度相关的附加长度尺度。黑洞产生热粒子，导致黑洞完全蒸发，产生非发散纠缠熵、佩奇曲线翻转和无信息丢失的渐近量子纯态。
