静态球对称黑洞Dirac场的统计熵

Statistical entropy of the Dirac field of static spherically symmetric black holes

利用改进的brick wall模型 ,给出了一类静态球对称黑洞Dirac场的熵 ,结果表明 ,在取相同的截断因子时 ,Dirac场的熵均为标量场的熵的 7

A statistical entropy of the Dirac field of static spherically symmetric black holes is gvien in this paper by using the improved brick wall model. The result shows that all these entrpies 7/2 times as large as the entropy of a scalar field when the same cutting factors are taken.
