隧道效应产生的黑洞辐射特性

Properties of Black Hole Radiation From Tunnelling

Timothy Clifton

摘要:

我们考虑了与量子力学隧穿事件引起的黑洞蒸发有关的时空。结果表明,隧道发生的表面是不同的全球事件视界,这对辐射达到未来的零无限的后果。模拟了一个球形坍缩过程,并计算了在未来零无穷远处预计观测到的辐射。它示出,外部观察者见证了蒸发过程,开始作为隧道表面暴露,并结束作为坍缩对象通过其事件视界后面。示出了所发射的辐射的崩溃过程的敏感性。

英文摘要:

We consider the space-time associated with the evaporation of a black hole by quantum mechanical tunnelling events. It is shown that the surface through which tunnelling occurs is distinct from the global event horizon, and that this has consequences for the radiation reaching future null infinity. A spherical collapse process is modelled, and the radiation expected to be observed at future null infinity is calculated. It is shown that external observers witness an evaporation process that begins as the tunnelling surface is exposed, and ends as the collapsing object passes behind its event horizon. The sensitivity of emitted radiation to the collapse process is illustrated.
