论文摘要
Black Hole Echo是一个重要的可观察到的,可以帮助我们更好地理解重力理论。我们表明,非线性电动力黑孔可以接收标量扰动的多峰有效潜力,这可以引起回声。选择合适的参数后,有效电位可以表现出具有两个以上峰的结构。将初始波数据包放在峰之外释放的初始波数据包时,我们发现当有效电势从2到三个变化的峰值变化时,Echo的时域轮廓将分裂。这是黑洞回声的现象,可以通过重力波检测来确定黑洞的几何结构。
Black hole echo is an important observable that can help us better understand gravitational theories. We present that the non-linear electrodynamic black holes can admit the multi-peak effective potential for the scalar perturbations, which can give rise to the echoes. After choosing suitable parameters, the effective potential can exhibit a structure with more than two peaks. Putting the initial wave packet released outside the peaks, we find that the time-domain profile of the echo will split when the peaks of the effective potential change from two to three. This is a phenomenon of black hole echo and it might be possible to determine the geometric structure of the black hole according to this phenomenon through gravitational wave detection.
