Equivalence of two independent calculations of the higher order guiding center Lagrangian
F. I. Parra, I. Calvo, J. W. Burby +2
The difference between the guiding center phase-space Lagrangians derived in [J.W. Burby, J. Squire, and H. Qin, Phys. Plasmas {\bf 20}, 072105 (2013)] and [F.I. Parra, and I. Calv…
Gauge properties of the guiding center variational symplectic integrator
Jonathan Squire, Hong Qin, William M. Tang
Variational symplectic algorithms have recently been developed for carrying out long-time simulation of charged particles in magnetic fields. As a direct consequence of their deriv…
Geometric integration of the Vlasov-Maxwell system with a variational particle-in-cell scheme
Jonathan Squire, Hong Qin, William M. Tang
A fully variational, unstructured, electromagnetic particle-in-cell integrator is developed for integration of the Vlasov-Maxwell equations. Using the formalism of Discrete Exterio…
