Kerr-Newman黑洞的辐射谱

运用Damour-Ruffini方法研究Kerr-Newman黑洞粒子的Hawking辐射.在保持时空中总能量,总角动量和总电荷守恒的条件下,考虑辐射粒子对时空的反作用后,得到黑洞辐射谱不再是严格的纯热谱.在该结论中,不但含有辐射粒子能量的影响项,而且含有辐射粒子角动量对黑洞角动量的影响项.所给表达式与用隧穿方法得到的表达式一致.满足量子力学的幺正性原理.

Hawking radiation of Kerr-Newman black hole

Taking into consideration the radiation particle retroaction with the total energy, angular momentum and charge of spacetime conservation, using the Damour-Ruffini method, the Hawking radiation of particle from Kerr-Newman black hole are re-investigated. It is found that the Hawking radiation is not exactly pure thermal. Our conclusion not only contains the impact for the energy of the radiation particle, but also contains the impact for the angular momentum of particle to the angular momentum of black hole. The result is consistent with the works of Parikh and Wilczek, and satisfies the unitary theory of quantum mechanics.
