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…

Preliminary analyses on dynamics and thermodynamics of rotating regular black holes
Hao Yang, Chang-Jiang Yu, Yan-Gang Miao
We investigate the dynamic and thermodynamic laws governing rotating regular black holes. By analyzing dynamic properties, i.e., the interaction between scalar particles and rotati…
