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…
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…
Holographic heat engine efficiency of hyperbolic charged black holes
Wei Sun, Xian-Hui Ge
We consider a four-dimensional charged hyperbolic black hole as working matter to establish a black hole holographic heat engine, and use the rectangular cycle to obtain the heat e…
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…
Construction of explicit symplectic integrators in general relativity. III. Reissner-Nordstrom-(anti)-de Sitter black holes
Ying Wang, Wei Sun, Fuyao Liu +1
We give a possible splitting method to a Hamiltonian for the description of charged particles moving around the Reissner-Nordstrom-(anti)-de Sitter black hole with an external magn…
