摘要：
粒子模拟（PIC）是理论等离子体物理中重要研究工具。为求解带电粒子运动，鲍里斯方法已用超半个世纪。虽其精度不错，但对高精度数值求解器需求日增，新积分器不断涌现。本文提出用于非相对论动力学模拟的新型高精度粒子积分器——超鲍里斯积分器，并讨论其与三维旋转表示的联系。
英文摘要：
Particle-in-cell (PIC) simulation is one of the most important research tools in theoretical plasma physics. To solve the motion of charged particles, the Boris method (a.k.a. the Boris integrator/pusher/solver) has been used for more than a half century. Although the Boris solver has good accuracy, the demand for high-accuracy numerical solvers has been increasing, and new integrators have been actively developed. In this contribution, we present novel high-accuracy particle integrators, the hyper Boris integrators, for nonrelativistic kinetic simulations. We further discuss their connection to 3D rotation representations.
