更高维度的黑洞毛发

Black hole hair in higher dimensions

Chao Cao, Yi-Xin Chen, Jian-Long Li

摘要:

研究了D维时空中静态球对称黑洞与物质平衡时的性质。它要求这类物质有一个状态方程(ω \equiv p_r/ρ=-1/(1+2kn),k,\in \mathbb{N}),似乎与D无关。然而,当我们把它与特定的模型联系起来时,可以发现一些有趣的空间限制:(i)(D=2+2kn)当黑洞被宇宙弦包围时;(ii)只有在四维时空中,黑洞才能被线性介子场包围。在这两种情况下,D=4是特殊的。

英文摘要:

We study the property of matter in equilibrium with a static, spherically symmetric black hole in D-dimensional spacetime. It requires this kind of matter has an equation of state (ω\equiv p_r/ρ=-1/(1+2kn), k,n\in \mathbb{N}), which seems to be independent of D. However, when we associate this with specific models, some interesting limits on space could be found: (i)(D=2+2kn) while the black hole is surrounded by cosmic strings; (ii)the black hole can be surrounded by linear dilaton field only in 4-dimensional spacetime. In both cases, D=4 is special.
