Drift approximation by the modified Boris algorithm of charged-particle dynamics in toroidal geometry
Yanyan Shi
In this paper, we study the charged-particle dynamics under strong magnetic field in a toroidal axi-symmetric geometry. Using modulated Fourier expansions of the exact and numerica…

On a large-stepsize integrator for charged-particle dynamics
Christian Lubich, Yanyan Shi
Xiao and Qin [Computer Physics Comm., 265:107981, 2021] recently proposed a remarkably simple modification of the Boris algorithm to compute the guiding centre of the highly oscill…
