从压扁的Kaluza-Klein黑洞隧穿的霍金辐射

Hawking radiation as tunneling from squashed Kaluza-Klein black hole

Ken Matsuno, Koichiro Umetsu

摘要:

基于隧穿机制讨论了五维压缩Kaluza-Klein黑洞的霍金辐射.最近由Umetsu提出的一种简单的方法,可以将Parikh和Wilczek的原始推导推广到各种黑洞。也就是说,我们使用二维有效度量,这是通过在视界附近降维得到的,作为背景度量。用同样的方法,我们得到了在压缩的Kaluza-Klein黑洞背景中霍金温度和辐射的反反应效应的理想结果。

英文摘要:

We discuss Hawking radiation from a five-dimensional squashed Kaluza-Klein black hole on the basis of the tunneling mechanism. A simple manner, which was recently suggested by Umetsu, is possible to extend the original derivation by Parikh and Wilczek to various black holes. That is, we use the two-dimensional effective metric, which is obtained by the dimensional reduction near the horizon, as the background metric. By using same manner, we derive both the desired result of the Hawking temperature and the effect of the back reaction associated with the radiation in the squashed Kaluza-Klein black hole background.
