Metriplectic foundations of gyrokinetic Vlasov-Maxwell-Landau theory
Published 16 Mar 2022 in physics.plasm-ph and physics.class-ph | (2203.08464v1)
Abstract: This letter reports on a metriplectic formulation of collisional, nonlinear full-$f$ electromagnetic gyrokinetic theory compliant with energy conservation and monotonic entropy production. In an axisymmetric background magnetic field, the toroidal angular momentum is also conserved. Notably, a new collisional current, contributing to the gyrokinetic Maxwell-Amp`ere equation and the gyrokinetic charge conservation law, is discovered.
