Black Holes Trapped by Ghosts
Cheng-Yong Zhang, Yunqi Liu, Bin Wang
Violent cosmic events, from black hole mergers to stellar collapses, often leave behind highly excited black hole remnants that inevitably relax to equilibrium. The prevailing view…

Nonlinear self-interaction induced black hole bomb
Cheng-Yong Zhang, Qian Chen, Yuxuan Liu +3
We present the first alternative mechanisms to trigger black hole bomb phenomena beyond the famous superradiant instability. By incorporating nonlinear self-interaction into the ma…

Nonlinear dynamics of hot, cold and bald Einstein-Maxwell-scalar black holes in AdS spacetime
Qian Chen, Zhuan Ning, Yu Tian +2
We investigate the dynamical transition processes of an Einstein-Maxwell-scalar gravitational system between two local ground states and an excited state in the anti-de Sitter spac…
