论文摘要
我们研究了爱因斯坦 - 马克斯韦 - 斯卡尔理论中标量的带电的黑洞，其两个u（1）字段受到$ n = 4 $ supergravity的启发。 From the onset of the spontaneous scalarization (tachyonic instability of Reissner-Nordström black hole), these black holes are classified by the number of $n=0,1,2,\cdots$, where $n=0$ is called the fundamental black hole and $n=1,2,\cdots$ denote the $n$-excited black holes.采用径向扰动，我们表明$ n = 0 $黑洞是稳定的，而$ s（l = 0）$ - 模式标量扰动，而$ n = 1,2 $兴奋的黑洞不稳定。这意味着$ n = 0 $黑洞被视为Reissner-Nordström黑洞的终点。
We investigate scalarized charged black holes in the Einstein-Maxwell-Scalar theory with two U(1) fields inspired by the $N=4$ supergravity. From the onset of the spontaneous scalarization (tachyonic instability of Reissner-Nordström black hole), these black holes are classified by the number of $n=0,1,2,\cdots$, where $n=0$ is called the fundamental black hole and $n=1,2,\cdots$ denote the $n$-excited black holes. Adopting radial perturbations, we show that the $n=0$ black hole is stable against the $s(l=0)$-mode scalar perturbation, whereas the $n=1,2$ excited black holes are unstable. This implies that the $n=0$ black hole is considered as an endpoint of the Reissner-Nordström black hole.
