利用Damour-Ruffini方法研究了Reissner-Nordstrom黑洞的Hawking辐射,在考虑辐射能量对背景时空反作用的情况下,发现辐射谱不再是理想的热谱.得到的修正后的Hawking辐射谱,有可能从黑洞中带出信息,进而用来解释黑洞信息丢失佯谬问题,同时满足量子理论的幺正性.这里的讨论不仅适合于无静止质量的粒子,而且适合于有静止质量的粒子;不仅适合于标量粒子,而且适合于Dirac粒子;具有广泛的适用性.
Taking into consideration the self-gravitational interaction and energy conservation, Hawking radiation from Reissner- Nordstrom black hole is re-investigated using the Damour-Ruffini method. It is found that the radiation is not exactly thermal, and the non-thermal Hawking radiation can carry information from the black hole. This can be used to explain the black hole information paradox, and the process satisfies the unitary thoery. A new method to calculate the corrected non-thermal Hawking radiation is given, which is more general. It can be used to study not only both the scalar field and Dirac field, but also massive and massless particle radiations.
