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…
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…
Spontaneous scalarization of Bardeen black holes
Lina Zhang, Qiyuan Pan, Yun Soo Myung +1
We study the spontaneous scalarization of Bardeen black holes, whose tachyonic instability triggers the formation of scalarized charged black holes (SCBHs). In this case, we find i…
Charged dilatonic black holes in dilaton-massive gravity
Lina Zhang, Qiyuan Pan, Bo Liu +2
In this paper, we focus on massive Einstein-dilaton gravity including the coupling of dilaton scalar field to massive graviton terms, and then derive static and spherically symmetr…
