黑洞视界的恶作剧：对的创造还是博尔韦尔吸积？
Shenanigans at the black hole horizon: pair creation or Boulware accretion?
摘要：
目前关于黑洞蒸发的理论认为，霍金能流$F$是由视界处的电子对产生提供动力的。然而，电子对的产生产生了纠缠，其中一些必须在黑洞完全蒸发之前被打破。这会导致信息的丢失和对统一性的破坏。在本文中，另一种情况下，建议再现霍金蒸发的基本特征，但不调用对创建与随之而来的问题。在这个“博尔韦尔吸积”的场景中，正通量$F$在无穷远处仍然是流出的，但在视界附近它变成了负能量的流入。这个负的能量通量（勉强）满足弗拉纳根能量不等式。
英文摘要：
The current scenario of black hole evaporation holds that the Hawking energy flux $F$ is powered by pair creation at the horizon. However, pair creation produces entanglements, some of which must necessarily be broken before the black hole evaporates completely. That leads to loss of information and violation of unitarity. In this paper, an alternative scenario is suggested that reproduces the essential features of Hawking evaporation, but does not invoke pair creation with its attendant problems. In this "accreting Boulware" scenario, a positive flux $F$ is still an outflux at infinity, but near the horizon it becomes an influx of negative energy. This negative energy flux (marginally) satisfies the Flanagan energy inequality.
