Relativistic Motion in a Constant Electromagnetic Field

Siu A. Chin

For a relativistic charged particle moving in a constant electromagnetic field, its velocity 4-vector has been well studied. However, despite the fact that both the electromagnetic…

The physics of symplectic integrators: perihelion advances and symplectic corrector algorithms

Siu A. Chin

Symplectic integrators evolve dynamical systems according to modified Hamiltonians whose error terms are also well-defined Hamiltonians. The error of the algorithm is the sum of ea…

A Fundamental Theorem on the Structure of Symplectic Integrators

Siu A. Chin

I show that the basic structure of symplectic integrators is governed by a theorem which states {\it precisely}, how symplectic integrators with positive coefficients cannot be cor…

The Complete Characterization of Fourth-Order Symplectic Integrators with Extended-Linear Coefficients

Siu A. Chin

The structure of symplectic integrators up to fourth-order can be completely and analytical understood when the factorization (split) coefficents are related linearly but with a un…

Forward Symplectic Integrators and the Long Time Phase Error in Periodic Motions

S. R. Scuro, S. A. Chin

We show that when time-reversible symplectic algorithms are used to solve periodic motions, the energy error after one period is generally two orders higher than that of the algori…

Exact evolution of time-reversible symplectic integrators and their phase error for the harmonic oscillator

Siu A. Chin, Sante R. Scuro

The evolution of any factorized time-reversible symplectic integrators, when applied to the harmonic oscillator, can be exactly solved in a closed form. The resulting modified Hami…
