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.enAttribution-NonCommercial-ShareAlike 3.0 United StatesBlack holesType of access: Open AccessResearch Subject Categories::NATURAL SCIENCESDynamical casimir effectHawking radiationMoving mirrorsArticle
