摘要: 采用Parikh量子隧穿方法,研究了一个环似(atorus-like)黑洞的量子隧穿效应.结果表明在能量守恒的条件下,此黑洞事件视界和宇宙视界处粒子的隧穿率与Bekenstein-Hawking熵有关,真实的辐射谱不再是严格的纯热谱,这是对Hawking纯热谱的正确修正.Abstract: Applying the Parikh’s quantum tunneling method,it was studied that the tunneling radiation characteristics of a torus-like black hole.The result shows that the tunneling rate of particle at the event horizon and the cosmic horizon is relevant to Bekenstein-Hawking entropy,and the radiation spectrum is not strictly pure thermal.This is a right correction to Hawking radiation.
