非阿贝尔磁黑弦与黑洞
Non-abelian magnetic black strings versus black holes
摘要:
本文提出了由$d-$维Einstein-Yang-Mills-Dilaton黑洞诱导的$d+1-$维纯磁性Yang-Mills(YM)黑弦(或$1-$膜). Born-Infeld版本的YM场使我们的出发点通过限制过程到达标准YM场。从黑洞到黑弦的提升(场的数量更少)是通过增加一个额外的紧凑坐标。这相当于从$S^{d-2}$到产品结构的水平拓扑变化。$5-$维中的黑弦是一种非常特殊的弦,具有均匀的Hawking温度和非渐近平坦的结构。当YM电荷变大时,弦变细,趋于断裂点,并转变为$4-$ %维黑洞。
英文摘要:
We present $d+1-$dimensional pure magnetic Yang-Mills (YM) black strings (or $1-$branes) induced by the $d-$dimensional Einstein-Yang-Mills-Dilaton black holes. Born-Infeld version of the YM field makes our starting point which goes to the standard YM field through a limiting procedure. The lifting from black holes to black strings, (with less number of fields) is by adding an extra, compact coordinate. This amounts to the change of horizon topology from $S^{d-2}$ to a product structure. Our black string in $5-$dimensions is a rather special one, with uniform Hawking temperature and non-asymptotically flat structure. As the YM charge becomes large the string gets thinner to tend into a breaking point and transform into a $4-$% dimensional black hole.
