论文摘要

我们研究了五维的爱因斯坦 - 马克斯韦尔理论中的平滑气泡空间,在kaluza-klein还原上类似于四维磁性黑洞。我们将它们表示为拓扑恒星,因为它们具有由磁通量支撑的拓扑周期。与Kaluza-Klein圆圈的大小相比,它们在宏观上可能是宏观的,并且可以描述天体物理黑洞微晶格几何的定性特性。我们还描述了没有曲率奇异性的五维黑色弦,内部盖是带有气泡的二维Milne空间。

We study smooth bubble spacetimes in five-dimensional Einstein-Maxwell theory that resemble four-dimensional magnetic black holes upon Kaluza-Klein reduction. We denote them as Topological Stars since they have topological cycles supported by magnetic flux. They can be macroscopically large compared to the size of the Kaluza-Klein circle and could describe qualitative properties of microstate geometries for astrophysical black holes. We also describe five-dimensional black strings without curvature singularity, the interior caps as a two-dimensional Milne space with a bubble.
