Parikh最近将黑洞辐射视为半经典的隧穿过程,在考虑了自引力相互作用后,得出静态球对称Schwarzschild和Reissner-Nordstrm黑洞的辐射谱不是纯热谱.采用Doran给出的Kerr黑洞解的新形式,将Parikh的工作推广到Kerr黑洞,研究转动黑洞的隧穿辐射,得到了修正的辐射谱,它与黑洞的Bekenstein-Hawking熵变有关,不是纯热谱,但满足量子力学中的幺正性原理.

Parikh recently viewed the black hole radiation as a semi-classical tunneling process, and showed that the radiation spectrum for the static Schwarzschild and Reissner-Nordstrm black holes is not pure thermal after considering the self-gravity interaction. In this paper, we adopt the new form of the Kerr solution presented by Doran and extend Parikh's work to investigate the tunneling radiation of a rotating black hole. We obtain a corrected radiation spectrum, which is related to the change of Bekenstein-Hawking entropy. It is not pure thermal, but is consistent with the underlying unitary theory.-
