静态dilaton黑洞中带电磁荷粒子的隧穿效应

Charged particle tunneling in a static dilaton black hole

  • 摘要: 利用Parikh和wilczek的隧穿模型,在Gibbons-Maeda dilaton黑洞时空中,通过计算带有电荷和磁荷的粒子在事件视界上的隧穿慨率,研究了该黑洞的Hawking辐射.在粒子的隧穿过程中,强调了时空的能量守恒和电磁荷守恒,考虑了隧穿粒子对背景时空的反作用.计算表明,在Gibbons-Maedla dilaton黑洞时空中,带电磁荷的粒子通过事件视界的隧穿概率取决于粒子出射前后黑洞熵的变化.这表示,黑涧辐射过程中可以满足信息守恒和量子理论的幺正性.
    Abstract: In the Parikh and Wilczek' s tunneling framework, Hawking radiation of charged particle in the Gibbons-Maeda dilaton black hole is investigated. When a particle with electromagnetic charge tunnels across the event horizon, energy conservation and electromagnetic charge conservation of the spacetimes are emphasized and the back-reaction effects of the charged particle are considered .The present results show that the tunneling probability is related to the difference of the Benkenstin-Hawking entropy of the black hole. This implies that black hole radiation is consistent with information conservation and the underlying unitary theory.
