五维黑洞的隐共形对称性

Hidden Conformal Symmetries of Five-Dimensional Black Holes

Chethan Krishnan

摘要:

最近,Castro,Maloney和Strominger(CMS)证明了4D Kerr黑洞具有“隐藏的”共形对称性。利用Cvetic和Larsen的一些旧结果,我证明了这个结果很可能也适用于从杂化/II型弦论中产生的最一般的五维黑洞。特别是,我们展示了如何在这些几何形状中的波动方程在“近区”可以写在SL(2,R)× SL(2,R)Casimirs。对于黑洞具有两个自旋但不含U(1)荷的特殊情况,我们发现了CFT和几何之间熵和吸收截面的详细匹配,我们所考虑的黑洞不需要接近极值.

英文摘要:

Recently it was shown by Castro, Maloney and Strominger (CMS) that 4D Kerr black holes have a "hidden" conformal symmetry. Using some old results of Cvetic and Larsen, I show that this result is very likely to hold also for the most general black holes in five dimensions arising from heterotic/type II string theory. In particular, we show how the wave equation in these geometries in the "near region" can be written in terms of SL(2,R) X SL(2,R) Casimirs. For the special case when the black hole has two spins but no U(1) charges, detailed matches for entropy and absorption cross sections between CFT and geometry are found. The black holes we consider need not be close to extremality.
