The equations of motion of a single particle subject to an arbitrary electric and a static magnetic field form a Poisson system. We present a second-order time integration method which preserves well the Poisson structure and compare it to commonly used algorithms, such as the Boris scheme. All the methods are represented in a general framework of splitting methods. We use the so-called ϕ functions, which give efficient ways for both analyzing and implementing the algorithms.

Long term analysis of splitting methods for charged-particle dynamics
In this paper, we rigorously analyze the energy, momentum and magnetic moment behaviours of two splitting methods for solving charged-particle dynamics. The near-conservations of these invariants are
Energy behaviour of the Boris method for charged-particle dynamics
The Boris algorithm is a widely used numerical integrator for the motion of particles in a magnetic field. This article proves near-conservation of energy over very long times in the special cases
Error estimates of some splitting schemes for charged-particle dynamics under strong magnetic field
TLDR
Under the maximal ordering scaling case, a novel energy-preserving splitting scheme with computational cost per step independent from the strength of the magnetic field is proposed and in fact for a class of Lie-Trotter type splitting schemes, a uniform and optimal error bound is established.

TLDR
This work shows that exponential-splitting algorithms of any order for solving particle trajectories in a general electric and magnetic field can be systematically derived by use of the angular momentum operator of quantum mechanics.

TLDR
Free Lie algebra theory gives simple formulae for the number of determining equations for a method to have a particular order, and a new, more accurate way of applying the methods thus obtained to compositions of an arbitrary first-order integrator is described and tested.

Why is Boris algorithm so good
TLDR
It is shown that the Boris algorithm conserves phase space volume, even though it is not symplectic, making it an effective algorithm for the multi-scale dynamics of plasmas.
