Stability of a black hole under the deformation of an extended periodic potential
Shi-Jie Ma, Run-Qiu Yang
It has been shown that the spectrum of black hole quasi-normal modes is extremely sensitive to localized deformations of the geometry away from the potential peak. The deformation…
Near-Horizon Deformation of Metric and the Black Hole Instability
Shi-Jie Ma, Zhan-Feng Mai, Run-Qiu Yang
Recent time-domain analyses suggest that black hole stability may be sensitive to localized near-horizon geometric deformations, while the underlying spectral mechanism remains unc…
Numerical study on the robustness of the stability for stable black holes
Zhan-Feng Mai, Run-Qiu Yang
This paper numerically studies if the stability of a stable black hole is robust against the small perturbation on geometry near its event horizon. In an other word, we numerically…
Geodesics connecting end points of time-like interval in asymptotically AdS spacetime
Jia-Hao He, Run-Qiu Yang
This paper studies the geodesics connecting two time-like separated boundary points in asymptotically anti-de Sitter (AdS) spacetime. We find that in spherically symmetry Schwarzsc…
Spectral instability of black holes: relating the frequency domain to the time domain
Yiqiu Yang, Zhan-Feng Mai, Run-Qiu Yang +2
Recent work has shown that the quasinormal mode spectrum of black holes is unstable under small perturbations (of order ) of the radial potential, while the early time-domain ri…
