Intrinsic rotation driven by turbulent acceleration
Michael Barnes, Felix I. Parra
Differential rotation is induced in tokamak plasmas when an underlying symmetry of the governing gyrokinetic-Maxwell system of equations is broken. One such symmetry-breaking mecha…
Thermal disequilibration of ions and electrons by collisionless plasma turbulence
Yohei Kawazura, Michael Barnes, Alexander A. Schekochihin
Does overall thermal equilibrium exist between ions and electrons in a weakly collisional, magnetised, turbulent plasma---and, if not, how is thermal energy partitioned between ion…
: a mixed implicit-explicit, delta-f gyrokinetic code for general magnetic field configurations
Michael Barnes, Felix Parra-Diaz, Matt Landreman
Here we present details of a mixed implicit-explicit numerical scheme for the solution of the gyrokinetic-Poisson system of equations in the local limit. This scheme has been imple…
Turbulent heating in an inhomogeneous, magnetised plasma slab
M. Barnes, P. Abiuso, W. Dorland
Observational evidence in space and astrophysical plasmas with long collisional mean free path suggests that more massive charged particles may be preferentially heated. One possib…
