F(R)引力中扩展黑洞对标量场的散射

Scattering of Scalar Field by an Extended Black Hole in F(R) gravity

Saneesh Sebastian, V. C. Kuriakose

摘要:

本文用WKB方法研究了F(R)引力场中扩展黑洞周围标量场的散射。得到了近视界区、远离视界区和远离视界区的波函数,并计算了吸收截面。我们发现吸收截面与霍金温度的立方成反比。我们还用隧道方法计算了黑洞的Hawking温度。

英文摘要:

In this work we have studied the scattering of scalar field around an extended black hole in F(R) gravity using WKB method. We have obtained the wave function in different regions such as near the horizon region, away from horizon and far away from horizon and the absorption cross section are calculated. We find that the absorption cross section is inversely proportional to the cube of Hawking temperature. We have also evaluated the Hawking temperature of the black hole via tunneling method.
