Collisional Gyrokinetics Teases the Existence of Metriplectic Reduction

Physics of Plasmas, 2020
In purely non-dissipative systems, Lagrangian and Hamiltonian reduction have been proven to be powerful tools for deriving physical models with exact conservation laws.

Exceptional Points in Linear Gyrokinetics

Physics of Plasmas, 2008
When performing linear gyrokinetic simulations, it is found that various types of microinstabilities, which are usually considered as strictly separated, can actually be transformed into each other via continuous variations of the plasma parameters. This behavior can be explained in terms of so-called exceptional points, which have their origin in the ...

Krylov–Boholiubov Methods and Gyrokinetics

Physica Scripta, 2001
Summary: The asymptotic theory of charged particle motion in electromagnetic fields is developed for the general case of finite Larmor-radius effects by means of the Krylov-Bogoliubov averaging method. The correspondence between the general asymptotic methods, elaborated by M. Krylov and M. Bogoliubov, the quasi-particle description and gyrokinetics is

Generalized gyrokinetics

The Physics of Fluids, 1985
A nonlinear gyrokinetic formalism is developed which admits mean velocities comparable to thermal speeds in arbitrary magnetic field geometry. The theory is fully electromagnetic and does not employ an eikonal ansatz. The moments of the gyrokinetic distribution function, as well as the gyrokinetic equation it satisfies, are derived to first order in ...

On the gyrokinetic equilibrium

Physics of Plasmas, 2000
Recent developments in gyrokinetic-magnetohydrodynamics (MHD) theory and in electromagnetic gyrokinetic particle simulations raise the question of consistency between the gyrokinetic model and the fluid model. Due to the special characteristics of the guiding center coordinates, it is a nontrivial exercise to show this consistency.
