克尔黑洞的内视界隧道效应

TUNNELING EFFECT FROM INNER HORIZON OF KERR BLACK HOLE

为了满足能斯特定理,克尔黑洞的熵不但要与外视界的面积有关而且必须要与内视界的面积有关.然后我们计算了内视界的温度.最后研究了包括内视界在内的隧道效应,分别计算了外视界和内视界的隧穿概率,Γ+和Γ-,而总概率应为内外视界隧穿概率之积,Γ=Γ+.Γ-.我们发现总概率与Parikh的结果保持一致,信息守恒.

In order to satisfy the Nernst theorem, entropy of a Kerr black hole is redefined and entropy must depend not only on area of the outer horizon but also on area of the inner horizon. Then we calculated temperature of the inner horizon and found that the inner horizon can emit radiation. Tunneling effect including the inner horizon of the Kerr black hole was examined. Tunneling rate of the outer horizon Г＋ and the inner horizon Г- total tunneling rate Г should be the product of rates for the outer and inner horizon, Г=Г＋ ·Г-. It was found that total tunneling rate was in agreement with Parikh＇s standard result, and there was no information loss.
