摘要
利用改进后的brick-wall模型研究自旋为2的引力场对动态Vaidya黑洞熵的量子修正,作者发现,在动态Vaidya黑洞中,自旋为2的引力场的量子熵仍与黑洞的视界面积成正比;当选择与标量场相同的截断因子时,其熵为标量场的2倍,为Dirac场的4/7倍,引力场,标量场和Dirac场对黑洞熵的总贡献为38Ah.
Quantum correction to the entropy of a Vaidya black hole due to high spin fields of spin quantum number 2 is studied by improved brick-wall model. It is found that the entropy contributed by gravitationial field of Vaidya black hole is just two times scalar fields and 4/7 times Dirac fields, while the truncation factor is the same as scalar field. Further than that, the authors obtain that the total entropy contributed by gravilational fields,scalar fields and Dirae fields is 13/8Ah.
