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…

Type I critical dynamical scalarization and descalarization in Einstein-Maxwell-scalar theory
Jia-Yan Jiang, Qian Chen, Yunqi Liu +4
We investigated the critical dynamical scalarization and descalarization of black holes within the framework of the Einstein-Maxwell-scalar theory featuring higher-order coupling f…
