在四维规范超引力下研究了具有球视界的超对称静态双子黑洞的存在性.我们分析了它们存在的条件，并提供了一般的一阶流方程驱动的标量场和度量翘曲因子从渐近AdS4几何的地平线。我们工作在一个一般的对偶对称设置，它允许描述电和磁测量。我们还讨论了吸引子机制和模（去）稳定的问题。
We investigate the existence of supersymmetric static dyonic black holes with spherical horizon in the context of $ mathcal{N} = 2 $ U(1) gauged supergravity in four dimensions. We analyze the conditions for their existence and provide the general first-order flow equations driving the scalar fields and the metric warp factors from the asymptotic AdS4 geometry to the horizon. We work in a general duality-symmetric setup, which allows to describe both electric and magnetic gaugings. We also discuss the attractor mechanism and the issue of moduli (de-)stabilization.
