圈量子引力中的黑洞态计数

Black hole state counting in loop quantum gravity

A. Ghosh, P. Mitra

摘要:

详细讨论了圈量子引力U(1)公式中计算黑洞微观态的两种方法,一种是计算所有允许的自旋网络标记j,m,另一种是只计算m个标记.阐明了对m的约束,并讨论了通量量子数与m之间的映射。具有|m| =j的矩阵,有时会被寻求,仅当涉及大面积时才显示出重要性。讨论扩展到SU(2)公式。

英文摘要:

The two ways of counting microscopic states of black holes in the U(1) formulation of loop quantum gravity, one counting all allowed spin network labels j,m and the other only m labels, are discussed in some detail. The constraints on m are clarified and the map between the flux quantum numbers and m discussed. Configurations with |m|=j, which are sometimes sought after, are shown to be important only when large areas are involved. The discussion is extended to the SU(2) formulation.
