论文摘要
我们计算在高度阻尼状态下使用高斯 - 骨网校正的D维大球体对称黑洞的准频率。我们在扰动上求解主微分方程,并在不同的轮廓中计算主扰动变量(分析上持续到复杂平面)的单层,以获得准标准模式光谱。我们考虑了张力,矢量和标量重力扰动,在爱因斯坦重力中获得了三种情况的相同频率。我们还针对测试标量字段分别执行相同的计算。
We compute the quasinormal frequencies of d-dimensional large spherically symmetric black holes with Gauss-Bonnet corrections in the highly damped regime. We solve perturbatively the master differential equation and we compute the monodromies of the master perturbation variable (analytically continued to the complex plane) in different contours, in order to obtain the quasinormal mode spectra. We consider tensorial, vectorial and scalar gravitational perturbations, obtaining the same frequencies for the three cases like in Einstein gravity. We also separately perform the same calculation for test scalar fields.
