Curvature-induced scalarization of charged AdS black holes

Chao-Ming Zhang, Yun Soo Myung, Lina Zhang +2

We investigate how a negative cosmological constant affects the Gauss-Bonnet (GB) scalarization in the Einstein-Maxwell-scalar-Gauss-Bonnet theory with a scalar coupling constant $…

Charge-dependent scalarization of Einstein- Euler-Heisenberg black holes

Lina Zhang, Yun Soo Myung, De-Cheng Zou +1

Charge-dependent scalarization of the Einstein-Euler-Heisenberg (EEH) black hole is carried out in the EEH-scalar theory by introducing an exponential scalar coupling with cou…

Newly scalarization of the Einstein-Euler-Heisenberg black hole

Lina Zhang, De-Cheng Zou, Yun Soo Myung

Th spontaneous scalarization of the Einstein-Euler-Heisenberg (EEH) black hole is performed in the EEH-scalar theory by introducing an exponential scalar coupling (with coupli…

Chaotic motion of particles around a dyonic Kerr-Newman black hole immersed in the Melvin-swirling universe

Deshui Cao, Lina Zhang, Songbai Chen +2

We employ the Poincaré section, fast Lyapunov indicator, recurrence analysis, bifurcation diagram and basins of attraction to investigate the dynamical behaviors of the motion of…

Spontaneous scalarization of regular Hayward black holes in Einstein-nonlinear electromagnetic-scalar gravity

Lan-Lan Cai, Meng-Yun Lai, De-Cheng Zou +2

Regular Hayward black holes provide a useful setting for investigating scalarization in theories with nonminimally coupled matter sectors. Within the framework of Einstein-nonlinea…

Chaotic motion of particles in the spacetime of a Kerr black hole immersed in swirling universes

Deshui Cao, Lina Zhang, Songbai Chen +2

We investigate the motion of particles in the spacetime of a Kerr black hole immersed in swirling universes. Using the Poincaré section, fast Lyapunov exponent indicator, bifurcat…
