含整体单极子的Vaidya-de Sitter黑洞的隧穿效应及辐射修正谱

Tunnelling Effect of Vaidya-de Sitter Black Hole with a Global Monopole and Corresponding Radiation Correction Spectrum

将Parikh-Wilczek的半经典隧穿方法推广到含整体单极子的Vaidya-deSitter黑洞.注意到Hawking辐射是黑洞事件视界附近由于真空涨落而引发的一种量子隧穿,在考虑辐射粒子自引力作用的情况下,计算了粒子的隧穿率及其相应的辐射修正谱,结果满足量子理论的幺正性定理.

In this paper,we extend Parikh and Wilczek＇s semiclassic tunneling method to the Vaidya-de Sitter black hole with a global monopole.Paying attention to that Hawking radiation is a quatum tunnelling of the lack hole event horizon by vaccum fluctuation,we and calculate the tunneling probability when self-gravitation is taken into account.We also obtain the corresponding radiation correction spectrum,the result is consistent with an underlying unitary theory.
