A solvable model of Vlasov-kinetic plasma turbulence in Fourier-Hermite phase space
T. Adkins, A. A. Schekochihin
A class of simple kinetic systems is considered, described by the 1D Vlasov-Landau equation with Poisson or Boltzmann electrostatic response and an energy source. Assuming a stocha…
Disruption of Alfvénic turbulence by magnetic reconnection in a collisionless plasma
A. Mallet, A. A. Schekochihin, B. D. G. Chandran
We calculate the disruption scale at which sheet-like structures in dynamically aligned Alfvénic turbulence are destroyed by the onset of magnetic reconnection in a low…
Kinetic simulations of the interruption of large-amplitude shear-Alfvén waves in a high-beta plasma
J. Squire, M. W. Kunz, E. Quataert +1
Using two-dimensional hybrid-kinetic simulations, we explore the nonlinear "interruption" of standing and traveling shear-Alfvén waves in collisionless plasmas. Interruption involv…
Ion-scale turbulence in MAST: anomalous transport, subcritical transitions, and comparison to BES measurements
F. van Wyk, E. G. Highcock, A. R. Field +4
We investigate the effect of varying the ion temperature gradient (ITG) and toroidal equilibrium scale sheared flow on ion-scale turbulence in the outer core of MAST by means of lo…
Laboratory evidence of dynamo amplification of magnetic fields in a turbulent plasma
P. Tzeferacos, A. Rigby, A. Bott +27
Magnetic fields are ubiquitous in the Universe. Extragalactic disks, halos and clusters have consistently been shown, via diffuse radio-synchrotron emission and Faraday rotation me…
Amplitude limits and nonlinear damping of shear-Alfvén waves in high-beta low-collisionality plasmas
Jonathan Squire, Alexander Schekochihin, Eliot Quataert
This work, which extends Squire et al. [ApJL, 830 L25 (2016)], explores the effect of self-generated pressure anisotropy on linearly polarized shear-Alfvén fluctuations in low-coll…
