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…

Charged particle motions near non-Schwarzschild black holes with external magnetic fields in modified theories of gravity
Hongxing Zhang, Naying Zhou, Wenfang Liu +1
A small deformation controlled by four free parameters to the Schwarzschild metric could be referred to a nonspinning black hole solution in alternative theories of gravity. Becaus…

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…
