摘要:

用砖墙模型的方法,讨论了无源电磁、中微子场对Barriola Vilenkin黑洞熵的量子修正。计算表明,量子修正应该包含两部分:其中一部分与视界面积成正比,在视界附近与紫外截断因子∈是平方反比发散的;另一部分是两个对数发散项,这部分除了与黑洞的本身特征性质有关以外,还与自旋场的自旋有关。结果与标量场引起的量子修正具有完全不同的形式。

Abstract:

The quantum corrections to the entropy of the Barriola Vilenkin black  hole due to the gravitation electromagnetic and neutrino fields are calculated b y using the  brick wall model. It is shown that the quantum corrects consist in two parts :  One is aquadratic divergent term at event horizon and is proportional to t he s urface area of the event horizon. The other is two logarithmically divergent terms which not only depend on the characteristics of the black hole but also on th e spin of fields. The whole expression does not take the form of the scalar field.

 

Key words: Quantum corrects, Barriola Vilenkin black hole, Entropy
