最近的工作将霍金辐射看作是Schwarzschild和Reissner-Nordstr“om时空视界上的半经典隧穿过程，在考虑了黑洞的动力学背景和能量守恒后，霍金辐射的精确辐射谱不再是纯热的.在本文中，我们扩展的方法，考虑到能量守恒，角动量守恒和电荷守恒的情况下，研究霍金辐射作为无质量粒子隧穿Kerr黑洞的事件视界和从Kerr-Newman黑洞的带电粒子的事件视界。结果表明，考虑自引力时，隧穿率与Bekenstein-Hawking熵的变化有关，得到的发射谱偏离了纯热谱，但与幺正理论一致.
Recent work, which treats the Hawking radiation as a semiclassical tunneling process at the horizon of the Schwarzschild and Reissner-Nordstr\"om spacetimes, indicates that the exact radiant spectrum is no longer pure thermal after considering the black hole background as dynamical and the conservation of energy. In this paper, we extend the method to investigate Hawking radiation as massless particles tunneling across the event horizon of the Kerr black hole and that of charged particles from the Kerr-Newman black hole by taking into account the energy conservation, the angular momentum conservation, and the electric charge conservation. Our results show that when self-gravitation is considered, the tunneling rate is related to the change of Bekenstein-Hawking entropy and the derived emission spectrum deviates from the pure thermal spectrum, but is consistent with an underlying unitary theory.
