论文摘要

我们研究了新型4D带电的爱因斯坦 - 加斯 - 鲍尼特黑洞的上级和稳定性,该黑洞最近受到Glavan和Lin [Phys的启发。莱特牧师。 124,081301(2020)]。我们发现,正高斯 - 骨网耦合$α$ $α$增强了超高感,而负$α$抑制了超级。证明了超级不稳定性的状况。我们还研究了带电的爱因斯坦 - 加斯 - 邦纳特黑洞的准模式(QNM),发现所有QNM的实际部分都生活在超级条件之外,而虚构的部分都是负面的。因此,这个黑洞是超级稳定的。当$α$成为Black Hole极值时,会有正常模式。

We investigated the superradiance and stability of the novel 4D charged Einstein-Gauss-Bonnet black hole which is recently inspired by Glavan and Lin [Phys. Rev. Lett. 124, 081301 (2020)]. We found that the positive Gauss-Bonnet coupling consant $α$ enhances the superradiance, while the negative $α$ suppresses it. The condition for superradiant instability is proved. We also worked out the quasinormal modes (QNMs) of the charged Einstein-Gauss-Bonnet black hole and found that the real part of all the QNMs live beyond the superradiance condition and the imaginary parts are all negative. Therefore this black hole is superradiant stable. When $α$ makes the black hole extremal, there are normal modes.
