五维旋转带电黑洞的Hawking辐射

利用Damour—Ruffini方法，对五维旋转带电时空背景下黑洞的Hawking辐射谱与辐射温度进行了研究。在计算过程中，取时空中总能量守恒、总角动量守恒和总电荷守恒，并考虑黑洞辐射粒子对时空的反作用。发现黑洞辐射谱不再是严格的纯热谱，辐射谱与黑洞的Bekenstein—Hawking熵差有关。计算结果表明，不仅黑洞辐射谱满足量子理论的幺正性，而且能给出黑洞辐射的整个过程。

Hawking Radiation of 5-dimensional Rotating Charged Black Holes

We extend the classical Damour-Ruffini method and under the condition that the total energy and angular momentum and electric charge of spacetime are conservative, taking the radiation particle reaction to the spacetime into consideration, we discuss Hawking radiation temperature and spectrum of five-dimensional charged black hole. We obtain that the black hole radiation spectrum is not pure thermal spectrum, which is related with the difference of the Bekenstein-Hawking entropy. We not only derive the radiation spectrum that satisfies the unitary principle in general case but also display the whole radiation process of the black hole.
