摘要
尽管黑洞信息丢失之谜的完整解释要在量子引力或弦理论的框架内完成,但是为解决黑洞信息丢失之谜,用半经典的隧穿方法研究了球对称荷电黑洞的隧穿辐射特征.其结果表明隧穿率与Bekenstein-Hawk-ing熵的改变有关,辐射谱不是纯热谱,信息丢失是可能的,满足量子力学中的幺正性原理.这不仅是对Hawk-ing辐射谱的进一步修正,而且提供了研究黑洞荷电粒子隧穿辐射的新方法.
Although the intensive explanation for the puzzle of the information loss needs the quantum gravitation theory or the string theory, the semi-classical tunneling method is used for investigating the tunneling radiation characteristics of the spherically symmetric charged black hole. The result shows that the tunneling rate is related to the change of the Bekenstein-Hawking entropy and the radiation spectrum is not strictly thermal. Thereby the information loss is possible, which satisfies the underlying unitary theory of the quantum mechanics. And it provides not only a further modification to the Hawking radiation spectrum but also a new method to study the quantum tunneling radiation of charged particles.
