论文摘要
在现代理论物理学中，与黑洞霍金蒸发相关的信息损失悖论是一个尚未解决的问题。在最近的简短文章中，我们通过量子状态的欧几里得路径积分（EPI）重新审视了黑洞纠缠熵的演变，并允许沿Lorentzian Evolution的半古典历史分支。我们认为，至少有两个历史对EPI有贡献，其中一个历史是信息丢失的历史，而另一个是信息传播的历史。在早期，前者占主导地位，而在后期，后者占主导地位。通过这样做，我们恢复了页面曲线的本质，因此单位性，尽管有转折点，即页面时间，很大程度上转向了较晚的时间。在这篇全长论文中，我们填写了我们的论点和计算的细节，以加强我们的概念。这种修改后的页面曲线的含义是熵界可能会受到侵犯。我们评论我们的方法与复制虫洞和岛屿猜想之间的相似性和差异。
The information loss paradox associated with black hole Hawking evaporation is an unresolved problem in modern theoretical physics. In a recent brief essay, we revisited the the evolution of the black hole entanglement entropy via the Euclidean path integral (EPI) of the quantum state and allow for the branching of semi-classical histories along the Lorentzian evolution. We posited that there exist at least two histories that contribute to EPI, where one is an information-losing history while the other is information-preserving. At early times, the former dominates EPI, while at late times the latter becomes dominant. By so doing we recovered the essence of the Page curve and thus the unitarity, albeit with the turning point, i.e., the Page time, much shifted toward the late time. In this full-length paper, we fill in the details of our arguments and calculations to strengthen our notion. One implication of this modified Page curve is that the entropy bound may thus be violated. We comment on the similarity and difference between our approach and that of the replica wormholes and the islands conjectures.
