A Hamiltonian gyrofluid model based on a quasi-static closure
E. Tassi, T. Passot, P. L. Sulem
A Hamiltonian six-field gyrofluid model is constructed, based on closure relations derived from the so-called "quasi-static" gyrokinetic linear theory where the fields are assumed…
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…
Fluid simulations of plasma turbulence at ion scales: comparison with Vlasov-Maxwell simulations
D. Perrone, T. Passot, D. Laveder +5
Comparisons are presented between a hybrid Vlasov-Maxwell (HVM) simulation of turbulence in a collisionless plasma and fluid reductions. These include Hall-magnetohydrodynamics (HM…
A new instability for finite Prandtl number rotating convection with free-slip boundary conditions
Yannick Ponty, Thierry Passot, Pierre-Louis Sulem
Rolls in finite Prandtl number rotating convection with free-slip top and bottom boundary conditions are shown to be unstable with respect to small angle perturbations for any valu…
Compressible dynamics of magnetic field lines for incompressible MHD flows
E. A. Kuznetsov, T. Passot, P. L. Sulem
It is demonstrated that the deformation of magnetic field lines in incompressible magnetohydrodynamic flows results from a compressible mapping. Appearance of zeroes for the mappin…
