Chaos dynamics of charged particles near Gibbons-Maeda-Garfinkle-Horowitz-Strominger black holes
Zhen-Meng Xu, Da-Zhu Ma, Kai Li
The Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) dilatonic black hole, a key solution in low-energy string theory, exhibits previously unexplored chaotic dynamics for charge…

Chaotic motion of the charged test particle in a Kerr-MOG black hole with explicit symplectic algorithms
Zhen-Meng Xu, Da-Zhu Ma, Wen-Fu Cao +1
The Kerr-MOG black hole has recently attracted significant research attention and has been extensively applied in various fields. To accurately characterize the long-term dynamical…

Explicit symplectic integrators with adaptive time steps in curved spacetimes
Xin Wu, Ying Wang, Wei Sun +2
Recently, our group developed explicit symplectic methods for curved spacetimes that are not split into several explicitly integrable parts, but are via appropriate time transforma…
