摘 要:
采用Parikh量子隧穿方法,研究了一个环似(a torus—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.[著者文摘]

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.[著者文摘]
