Electron neural closure for turbulent magnetosheath simulations: energy channels
George Miloshevich, Luka Vranckx, Felipe Nathan de Oliveira Lopes +3
In this work, we introduce a non-local five-moment electron pressure tensor closure parametrized by a Fully Convolutional Neural Network (FCNN). Electron pressure plays an importan…
Hamiltonian reduction of Vlasov-Maxwell to a dark slow manifold
George Miloshevich, Joshua W. Burby
We show that nonrelativsitic scaling of the collisionless Vlasov-Maxwell system implies the existence of a formal invariant slow manifold in the infinite-dimensional Vlasov-Maxwell…
Inverse cascade and magnetic vortices in kinetic Alfvén-wave turbulence
George Miloshevich, Dimitri Laveder, Thierry Passot +1
A Hamiltonian two-field gyrofluid model for kinetic Alfvén waves (KAWs) in a magnetized electron-proton plasma, retaining ion finite-Larmor-radius corrections and parallel magnetic…
Modeling imbalanced collisionless Alfvén wave turbulence with nonlinear diffusion equations
George Miloshevich, Thierry Passot, Pierre-Louis Sulem
A pair of nonlinear diffusion equations in Fourier space} is used to study the dynamics of strong Alfvén-wave turbulence, from MHD to electron scales. Special attention is paid to…
Direction of cascades in a magnetofluid model with electron skin depth and ion sound Larmor radius scales
George Miloshevich, Philip J. Morrison, Emanuele Tassi
The direction of cascades in a two-dimensional model that takes electron inertia and ion sound Larmor radius into account is studied, resulting in analytical expressions for the ab…
Action Principles for Relativistic Extended Magnetohydrodynamics: A Unified Theory of Magnetofluid Models
Yohei Kawazura, George Miloshevich, Philip J. Morrison
Two types of Eulerian action principles for relativistic extended magnetohydrodynamics (MHD) are formulated. With the first, the action is extremized under the constraints of densi…
