论文摘要
我们通过采用径向扰动，对从爱因斯坦 - 马克斯韦尔 - 统一耦合标量（EMCS）理论获得的标量的带电黑洞进行稳定分析。 The targeting black holes include a single branch of scalarized charged black hole with the coupling parameter $α>0$ inspired by the constant scalar hairy black hole as well as infinite branches of $n=0(α\ge 8.019),1(α\ge 40.84),2(α\ge 99.89),\cdots$ scalarized charged black holes found through the spontaneous scalarization on Reissner-Nordström黑洞。事实证明，单个分支中的黑洞和$ n = 0 $黑洞在径向扰动上是稳定的，而$ n = 1，2 $兴奋的黑洞在EMCS理论中是不稳定的，具有二次和指数耦合。
We perform the stability analysis for the scalarized charged black holes obtained from Einstein-Maxwell-conformally coupled scalar (EMCS) theory by employing the radial perturbations. The targeting black holes include a single branch of scalarized charged black hole with the coupling parameter $α>0$ inspired by the constant scalar hairy black hole as well as infinite branches of $n=0(α\ge 8.019),1(α\ge 40.84),2(α\ge 99.89),\cdots$ scalarized charged black holes found through the spontaneous scalarization on the Reissner-Nordström black hole. It turns out that the black hole in the single branch and the $n = 0$ black hole are stable against radial perturbations, while the $n = 1, 2$ excited black holes are unstable in the EMCS theory with both quadratic and exponential couplings.
