霍金与昂鲁效应,或缓慢穿越黑洞视界的困难

Hawking versus Unruh effects, or the difficulty of slowly crossing a black hole horizon

Luis C. Barbado, Carlos Barceló, Luis J. Garay, Gil Jannes

摘要:

当分析不同观察者对霍金辐射的感知时,霍金效应与昂鲁效应混合在一起。这两种效应的分离在文献中并不总是清楚的。在这里,我们提出了一个不一致的解释,什么是霍金效应,什么是Unruh效应。适当的解释是重要的,以阐明什么样的影响,探测器可能会经历取决于它的轨迹和量子场的状态。在简化的假设下,我们引入了一个分离这两种效应的分析公式。武装与以前的解释,我们认为,对于一个自由落体探测器穿越视界没有经历高能量的影响,这是必要的,视界穿越是不试图在低速。

英文摘要:

When analyzing the perception of Hawking radiation by different observers, the Hawking effect becomes mixed with the Unruh effect. The separation of both effects is not always clear in the literature. Here we propose an inconsistency-free interpretation of what constitutes a Hawking effect and what an Unruh effect. An appropriate interpretation is important in order to elucidate what sort of effects a detector might experience depending on its trajectory and the state of the quantum field. Under simplifying assumptions we introduce an analytic formula that separates these two effects. Armed with the previous interpretation we argue that for a free-falling detector to cross the horizon without experiencing high-energy effects, it is necessary that the horizon crossing is not attempted at low velocities.
