论文摘要
我们研究了带电的4D带电的爱因斯坦 - 高斯 - 鲍尼特 - 添加剂黑洞中带电的无质量标量扰动的线性不稳定性，通过探索准模式。我们发现线性不稳定性是由超高启动触发的。当增加高斯 - 骨网耦合常数或黑洞电荷时，带电的无质量标量扰动变得更加不稳定。同时，降低} ADS半径将使带电的无质量标量扰动}更加稳定。给出了参数空间$（α，Q，λ）$中的稳定区域。此外，我们发现带电的无质量标量扰动对于较大的标量电荷更加不稳定。多物的模式比单极的模式更稳定。
We study the linear instability of the charged massless scalar perturbation in regularized 4D charged Einstein-Gauss-Bonnet-AdS black holes by exploring the quasinormal modes. We find that the linear instability is triggered by superradiance. The charged massless scalar perturbation becomes more unstable when increasing the Gauss-Bonnet coupling constant or the black hole charge. Meanwhile, decreasing} the AdS radius will make the charged massless scalar perturbation} more stable. The stable region in parameter space $(α,Q,Λ)$ is given. Moreover, we find that the charged massless scalar perturbation is more unstable for larger scalar charge. The modes of multipoles are more stable than that of the monopole.
