RN和SdS极值黑洞的吸收截面
Absorption cross section of RN and SdS extremal black hole
摘要：
利用WKB近似和视界波反射效应，得到了Reissner Nordstrom（RN）极值和Schwarzschild-de Sitter（SdS）极值黑洞视界附近标量波函数的性质.计算了RN极值和SdS极值黑洞在Klein-Gordon场中的吸收截面$σ_{abs}$.
英文摘要：
The nature of scalar wave functions near the horizon of Reissner Nordstrom (RN) extremal and Schwarzschild-de Sitter (SdS) extremal black holes are found using WKB approximation and the effect of reflection of waves from the horizon. The absorption cross section $σ_{abs}$ when RN extremal and SdS extremal black holes placed in a Klein-Gordon field is calculated.
