Dependence of Kinetic Plasma Turbulence on Plasma β [PDF]
Abstract We study the effects of plasma β (the ratio of plasma pressure to magnetic pressure) on the evolution of kinetic plasma turbulence using fully kinetic particle-in-cell simulations of decaying turbulence. We find that the plasma β systematically affects spectra, measures of intermittency, decay rates of turbulence fluctuations ...

Ion and Electron Acceleration in Fully Kinetic Plasma Turbulence [PDF]
Turbulence is often invoked to explain the origin of nonthermal particles in space and astrophysical plasmas. By means of 3D fully kinetic particle-in-cell simulations, we demonstrate that turbulence in low-β plasmas (β is the ratio of plasma pressure to

Ion-scale Transition of Plasma Turbulence: Pressure–Strain Effect [PDF]
We investigate properties of solar-wind-like plasma turbulence using direct numerical simulations. We analyze the transition from large, magnetohydrodynamic (MHD) scales to the ion characteristic ones using two-dimensional hybrid (fluid electrons and ...

Evidence for electron Landau damping in space plasma turbulence. [PDF]
How turbulent energy is dissipated in weakly collisional space and astrophysical plasmas is a major open question. Here, we present the application of a field-particle correlation technique to directly measure the transfer of energy between the turbulent

Identification of Active Magnetic Reconnection Using Magnetic Flux Transport in Plasma Turbulence [PDF]
Magnetic reconnection has been suggested to play an important role in the dynamics and energetics of plasma turbulence by spacecraft observations, simulations, and theory over the past two decades, and recently, by magnetosheath observations of MMS.

Thermal disequilibration of ions and electrons by collisionless plasma turbulence. [PDF]
Significance Large-scale astrophysical processes inject energy into turbulent motions and electromagnetic fields, which carry this energy to small scales and eventually thermalize it. How this energy is partitioned between ions and electrons is important

Relativistic Particle Transport and Acceleration in Structured Plasma Turbulence [PDF]
We discuss the phenomenon of energization of relativistic charged particles in three-dimensional incompressible MHD turbulence and the diffusive properties of the motion of the same particles.

Data-driven model discovery for plasma turbulence modelling
An important problem in nuclear fusion plasmas is the prediction and control of turbulence which drives the cross-field transport, thus leading to energy loss from the system and deteriorating confinement.
