Third type of spacetime with the coexistence of integrability and non-integrability

Junjie Lu, Xin Wu

The integrability or non-integrability of a spacetime usually refers to whether the motion of massive or massless particles in the spacetime is integrable or not. The standard blac…

Explicit symplectic methods in black hole spacetimes

Xin Wu, Ying Wang, Wei Sun +2

Many Hamiltonian problems in the Solar System are separable or separate into two analytically solvable parts, and thus give a great chance to the development and application of exp…

Dynamics of charged particles moving around Kerr black hole with inductive charge and external magnetic field

Xin Sun, Xin Wu, Yu Wang +3

We mainly focus on the effects of small changes of parameters on the dynamics of charged particles around the Kerr black hole surrounded by an external magnetic field, which can be…

Adjustment of force-gradient operator in symplectic methods

Lina Zhang, Xin Wu, Enwei Liang

Many force-gradient explicit symplectic integration algorithms have been designed for the Hamiltonian with kinetic energy $T(\mathbf{p})=\mathbf{p}…

Applying explicit symplectic integrator to study chaos of charged particles around magnetized Kerr black hole

Wei Sun, Ying Wang, Fuyao Liu +1

In a recent work of Wu, Wang, Sun and Liu, a second-order explicit symplectic integrator was proposed for the integrable Kerr spacetime geometry. It is still suited for simulating…

Construction of explicit symplectic integrators in general relativity. IV. Kerr black holes

Xin Wu, Ying Wang, Wei Sun +1

In previous papers, explicit symplectic integrators were designed for nonrotating black holes, such as a Schwarzschild black hole. However, they fail to work in the Kerr spacetime…
