静态黑洞周围的定域标量结构

Localized scalar structures around static black holes

D. C. Moreira, F. A. Brito, D. Bazeia

摘要:

在这项工作中,我们提出了一种方法来捕获静态时空中的标量场的解决方案,通过使用BPS形式和放松的一般协方差条件。我们专注于配置的背景几何描述拓扑黑洞,并提出了解析和数值解,除了讨论使用保守的电荷与这种场的配置。所得到的解是径向稳定的,由稳定性方程产生的零模可以解析地表示。

英文摘要:

In this work we address a way to capture scalar field solutions on static spacetimes by using BPS formalism and relaxing the general covariance condition. We focus on configurations where the background geometry describes topological black holes and present both analytical and numerical solutions, in addition to discussing the use of conserved charges associated to such field configurations. The obtained solutions are radially stable and the zero-mode arising from the stability equation can be written analytically.
