Structure-Preserving MHD-Driftkinetic Discretization for Wave-Particle Interactions
Byung Kyu Na, Stefan Possanner, Xin Wang
We present a structure-preserving discretization of the hybrid magnetohydrodynamics (MHD)-driftkinetic system for simulations of low-frequency wave-particle interactions. The model…
On the Poisson brackets of hybrid plasma models with kinetic ions and massless electrons
Yingzhe Li, Philip J. Morrison, Stefan Possanner +1
We investigate the conditions under which the Jacobi identity holds for a class of recently introduced anti-symmetric brackets for the hybrid plasma models with kinetic ions and ma…
The Linearized Vlasov-Maxwell System as a Hamiltonian System
Dominik Bell, Martin Campos Pinto, Stefan Possanner +1
We present a Hamiltonian formulation for the linearized Vlasov-Maxwell system with a Maxwellian background distribution function. We discuss the geometric properties of the model a…
Gyrokinetic theory with polynomial transforms: a model for ions and electrons in maximal ordering
Edoardo Zoni, Stefan Possanner
We propose a novel derivation of the gyrokinetic field-particle Lagrangian for non-collisional ion-electron plasmas in a magnetic background with strong variations (maximal orderin…
