Extended phase-space symplectic-like integrators for coherent post-Newtonian Euler-Lagrange equations
Guifan Pan, Xin Wu, Enwei Liang
Coherent or exact equations of motion for a post-Newtonian Lagrangian formalism are the Euler-Lagrange equations without any terms truncated. They naturally conserve energy {and} a…
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}…
High-order QED correction impacts on phase transition of the Euler-Heisenberg AdS black hole
Guan-Ru Li, Sen Guo, En-Wei Liang
Two-phase transition branches of the Euler-Heisenberg (EH) anti-de Sitter (AdS) black hole (BH) were derived from its phase transition critical behavior by Magos et al. [Phys. Rev.…
Construction of second-order six-dimensional Hamiltonian-conserving scheme
Shiyang Hu, Xin Wu, Enwei Liang
It is shown analytically that the energy-conserving implicit nonsymplectic scheme of Bacchini, Ripperda, Chen and Sironi provides a first-order accuracy to numerical solutions of a…
Ehrenfest's scheme and microstructure for regular-AdS black hole in the extended phase space
Sen Guo, En-Wei Liang
The regular (Bardeen)-AdS (BAdS) black hole (BH) in the extended phase space is taken as an example for investigating the BH phase transition grade from both macroscopic and micros…
Energy-conserving integrator for conservative Hamiltonian systems with ten-dimensional phase space
Shiyang Hu, Xin Wu, Enwei Liang
In this paper, an implicit nonsymplectic exact energy-preserving integrator is specifically designed for a ten-dimensional phase-space conservative Hamiltonian system with five deg…
