Quasinormal modes and AdS/CFT correspondence of a rotating BTZ-like black hole in the Einstein-bumblebee gravity
Fangli Quan, Zhong-Wu Xia, Rui Ding +2
We obtain exact expressions for the quasinormal modes (QNMs) of the massive scalar, fermionic and vector perturbations around a rotating BTZ-like black hole in the Einstein-bumbleb…

Echoes and quasi-normal modes of perturbations around Schwarzchild traversable wormholes
Hao Yang, Zhong-Wu Xia, Yan-Gang Miao
We investigate the waveforms and quasi-normal modes around Schwarzschild traversable wormholes under different field perturbations, including the scalar field, the electromagnetic…

Scalar fields around a rotating loop quantum gravity black hole: Waveform, quasi-normal modes and superradiance
Zhong-Wu Xia, Hao Yang, Yan-Gang Miao
The rotating loop quantum gravity black hole is a newly proposed non-singular black hole, which eliminates spacetime singularities when a regularization parameter is introduced thr…
