Variational principle for the parallelsymplectic representation of electromagnetic gyrokinetic theory
Abstract
The nonlinear (fullf) electromagnetic gyrokinetic VlasovMaxwell equations are derived in the parallelsymplectic representation from an Eulerian gyrokinetic variational principle. The gyrokinetic VlasovMaxwell equations are shown to possess an exact energy conservation law, which is derived by the Noether method from the gyrokinetic variational principle. Here, the gyrocenter Poisson bracket and the gyrocenter Jacobian contain contributions from the perturbed magnetic field. Lastly, in the fullf formulation of the gyrokinetic VlasovMaxwell theory presented here, the gyrocenter parallelAmpere equation contains a secondorder contribution to the gyrocenter current density that is derived from the secondorder gyrocenter ponderomotive Hamiltonian.
