Gibbons—Maeda Dilation黑洞的量子隧穿效应

运用Parikh的量子隧穿方法，研究了静态球对称Gibbons—Maeda dilation黑洞的量子隧穿效应．当考虑粒子的自引力作用和能量守恒时，Gibbons—Maeda dilation黑洞视界处的粒子隧穿率与Bekenstein—Hawking熵有关，黑洞真实的辐射谱不再是严格的纯热谱．本文所得隧穿率在特殊情况下与Schwarzschild黑洞的结果一致，在忽略ω的高次方项的条件下，可以得到Gibbons—Maeda dilation黑洞辐射的纯热谱．

Quantum Tunneling Characteristics of Gibbons-Maeda Dilation Black Hole

Applying the Parikh's quantum tunneling method,the quantum tunneling characteristics of the static spherically symmetric Gibbons-Maeda dilation black hole is researched.The result shows that the tunneling rate at the event horizon of the black hole is relevant to Bekenstein-Hawking entropy and the exact radiation spectrum is not pure thermal one when the self-gravitation and energy conservation are taken into consideration.Finally,we use the obtained results to reduce to static Schwarzschild black hole,and find that only ignoring the high-order polynomial of co the tunneling radiation spectrum is consistent with Hawking pure thermal one.
