Relativistic ponderomotive Hamiltonian of a Dirac particle in a vacuum laser field
D. E. Ruiz, C. L. Ellison, I. Y. Dodin
We report a point-particle ponderomotive model of a Dirac electron oscillating in a high-frequency field. Starting from the Dirac Lagrangian density, we derive a reduced phase-spac…

Comment on "Symplectic integration of magnetic systems": a proof that the Boris algorithm is not variational
C. L. Ellison, J. W. Burby, H. Qin
The Boris algorithm for integrating charged particle trajectories in electric and magnetic fields is popular due to its simple implementation, rapid iteration, and observed long-te…
