任意维Schwarzschild-de Sitter黑洞的Hawking隧穿辐射

Hawking Radiation of Arbitrarily Dimensional Schwarzschild-de Sitter Black Hole as Tunneling

运用Parikh模型,研究任意维Schwarzschild-de Sitter(SdS)黑洞的Hawking隧穿辐射.结果表明,黑洞视界处的隧穿率依赖于Bekenstein-Hawking(BH)熵的变化,如果考虑到熵的变化按出射粒子能量展开式中的高次项,辐射谱不再是纯热的谱.

Applying the method of Parikh, we study the Hawking radiation of arbitrarily dimensional Schwarzschildde Sitter （SdS） black hole as tunneling. It is shown that the tunneling rate is related with the change of Bekenstein- Hawking （BH） entropy and the energy spectrum is not exactly thermal any longer if higher-order terms of the expanded form of the change of the entropy in the tunneling particle＇ s energy are considered.
