拓扑星、黑洞和广义带电Weyl解

Topological Stars, Black holes and Generalized Charged Weyl Solutions

Ibrahima Bah, Pierre Heidmann

摘要:

我们构造光滑静态气泡解,表示为拓扑星,在五维爱因斯坦-麦克斯韦理论是渐近的$\mathbb{R}^{1,3}\times$ S $^1$。这些气泡是通过允许电磁通量包裹平滑的拓扑循环来支持的。这些解与非极值静态带电黑弦处于相同的状态,而非极值静态带电黑弦在四维空间中简化为黑洞。通过构造封闭形式的广义带电Weyl解,我们推广到多体构型。一般的解由拓扑星和堆叠在一条线上的黑弦组成,它们被电磁通量包裹。我们把IIB型弦论的解嵌入到S $^1\times$ T $^4$上。在这个框架下,带电外尔解提供了一类新的非超对称和非极值黑洞制度中的多个带电物体的弦论。

英文摘要:

We construct smooth static bubble solutions, denoted as topological stars, in five-dimensional Einstein-Maxwell theories which are asymptotic to $\mathbb{R}^{1,3}\times$S$^1$. The bubbles are supported by allowing electromagnetic fluxes to wrap smooth topological cycles. The solutions live in the same regime as non-extremal static charged black strings, that reduce to black holes in four dimensions. We generalize to multi-body configurations on a line by constructing closed-form generalized charged Weyl solutions in the same theory. Generic solutions consist of topological stars and black strings stacked on a line, that are wrapped by electromagnetic fluxes. We embed the solutions in type IIB String Theory on S$^1\times$T$^4$. In this framework, the charged Weyl solutions provide a novel class in String Theory of multiple charged objects in the non-supersymmetric and non-extremal black hole regime.
