摘要
运用量子力学中的WKB方法和隧穿效应对Hawking辐射中粒子在黑洞视界附近的径向运动进行讨论.然后以史瓦西黑洞为例,运用Parikh和Wilczek的方法计算出粒子的隧穿几率并发现这种几率跟黑洞熵的变化量有关,这一结论满足潜在的幺正原理.
Adopting the WKB method and tunneling effect in quantum mechanics, we discuss theradial motion of particles near the horizon of Hawking radiation. Then taking the Schwarzschild black hole as an example, we calculate particles＇ tunneling probability by the approach of Parikh and Wilczek and find that probability is related to the change of entropy of black hole, which is consistent with the underlying unitary theory.
