摘要:

利用 Brick wall 方法,计算非球坐标系,非渐近平直的 torus like 黑洞背景下标量场的自由能和熵. 结果表明,在非渐近平直时空,黑洞具有内外视界时,
所得熵不仅与外视界面积有关,而且也是内视界的函数.进一步证明,用内外视界参量表达的熵,在黑洞辐射温度趋于零时,黑洞的熵也趋于零,它满足能斯特定理,可视为黑洞的普朗克绝对熵.

关键词: Brick wall方法, 能斯特定理, 黑洞熵

Abstract:

Using brick wall method, the authors calculate the free energy and entropy o f the scalar  field on the background of non asympotic flat torus like black hole under the  sphere coordinates. The results show that the entropy not only is related to th e area of an outer horizon but also is the function of a inner horizon. Furtherm ore, the entropy expressed by inner and outer horizon will approach zero when th e radiation temperature of the black hole approaches zero. It satisfies the Nern st theorem. It can be taken as Planck absolute entropy.

Key words:  Brick wall method;Black hole entropy;Nernst theorem
