摘要

黑洞的似正规模被认为是黑洞的特征声音,对其进行研究可以让我们更加深入了解黑洞的性质.考虑到"量子涨落",黑洞时空度规需要进行修正.本文利用6阶WKB方法研究了量子修正Schwarzschild黑洞时空中电磁场扰动的似正规模.研究结果表明:由于"量子涨落"的存在,黑洞时空中电磁场的衰减变慢了,并且量子修正参数a的值越大,电磁场衰减得越慢.
        Quasinormal modes( QNMs) of black holes have been regarded as "characteristic sound"of black holes.Research on the QNMs can help us understand the properties of black holes deeply. Taking into account the"quantum fluctuations",the metric of black hole needs to be modified. In this paper,the 6thWKB method is adopted to study the QNMs of the electromagnetic perturbation in the space-time of quantum-corrected Schwarzschild black hole.The results show that due to the"quantum fluctuations",the electromagnetic field in the black hole damps more slowly,and the damping becomes slower and slower with the increase of the quantum-corrected parameter a.
