Chaos of charged particles near a renormalized group improved Kerr black hole in an external magnetic field
Junjie Lu, Xin Wu
In a quantum theory of gravity, a renormalization group improved Kerr metric is obtained from the Kerr metric, where the Newton gravitational constant is modified as a function of…
Chaos of charged particles in quadrupole magnetic fields under Schwarzschild backgrounds
Qihan Zhang, Xin Wu
A four-vector potential of an external test electromagnetic field in a Schwarzschild background is described in terms of a combination of dipole and quadrupole magnetic fields. Thi…
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…
Effects of Two Quantum Correction Parameters on Chaotic Dynamics of Particles Near Renormalized Group Improved Schwarzschild Black Holes
Junjie Lu, Xin Wu
A renormalized group improved Schwarzschild black hole spacetime contains two quantum correction parameters. One parameter represents the identification of cutoff of the distan…
Electromagnetic field and chaotic charged-particle motion around hairy black holes in Horndeski gravity
Wenfu Cao, Xin Wu, Jun Lyu
The Wald vector potential is an exact solution of the source-less Maxwell equations regarding an electromagnetic field of a vacuum uncharged black hole like the Kerr background bla…
