The Second Quadratic Invariant of Astrophysical Gyrokinetics
Benjamin D. G. Chandran, Alfred Mallet, Romain Meyrand
We show that gyrokinetics in a spatially uniform equilibrium (or `astrophysical gyrokinetics') possesses a previously unknown quadratic invariant, which we call the gyrokinetic hel…
Asymptotic scaling theory of electrostatic turbulent transport in magnetised fusion plasmas
T. Adkins, I. G. Abel, M. Barnes +8
Turbulent transport remains one of the principal obstacles to achieving efficient magnetic confinement in fusion devices. Two of the dominant drivers of the turbulence are microsca…
Turbulent heating in collisionless low-beta plasmas: imbalance, Landau damping, and electron-ion energy partition
T. Adkins, R. Meyrand, J. Squire
An understanding of how turbulent energy is partitioned between ions and electrons in weakly collisional plasmas is crucial for modelling many astrophysical systems. Using theory a…
Intermittent, Reflection-Driven, Strong Imbalanced MHD Turbulence
B. D. G. Chandran, N. Sioulas, S. Bale +4
We develop a phenomenological model of strong imbalanced magnetohydrodynamic (MHD) turbulence that accounts for intermittency and the reflection of Alfven waves by spatial variatio…
Generalized Expanding-Box Formulations of Reduced Magnetohydrodynamics in the Solar Wind
Vincent David, Benjamin D. G. Chandran, Romain Meyrand +2
We derive a set of simplified equations that can be used for numerical studies of reduced magnetohydrodynamic turbulence within a small patch of the radially expanding solar wind.…
The effects of finite electron inertia on helicity-barrier-mediated turbulence
T. Adkins, R. Meyrand, J. Squire
Understanding the partitioning of turbulent energy between ions and electrons in weakly collisional plasmas is crucial for the accurate interpretation of observations and modelling…
Fluidization of collisionless plasma turbulence
Romain Meyrand, Anjor Kanekar, William Dorland +1
In a collisionless, magnetized plasma, particles may stream freely along magnetic-field lines, leading to phase "mixing" of their distribution function and consequently to smoothin…
