A Field-Particle Correlation Analysis of a Perpendicular Magnetized Collisionless Shock: I. Theory
Gregory G. Howes, James Juno, Jason M. TenBarge +3
Collisionless shocks play an important role in space and astrophysical plasmas by irreversibly converting the energy of the incoming supersonic plasma flows into other forms, inclu…
A Field-Particle Correlation Analysis of a Perpendicular Magnetized Collisionless Shock
James Juno, Gregory G. Howes, Jason M. TenBarge +5
Using the field-particle correlation technique, we examine the particle energization in a 1D-2V continuum Vlasov--Maxwell simulation of a perpendicular magnetized collisionless sho…
Major Scientific Challenges and Opportunities in Understanding Magnetic Reconnection and Related Explosive Phenomena in Solar and Heliospheric Plasmas
H. Ji, J. Karpen, A. Alt +105
Magnetic reconnection underlies many explosive phenomena in the heliosphere and in laboratory plasmas. The new research capabilities in theory/simulations, observations, and labora…
Diagnosing collisionless energy transfer using field-particle correlations: Alfven-Ion Cyclotron Turbulence
Kristopher G. Klein, Gregory G. Howes, Jason M. TenBarge +1
We apply field-particle correlations -- a technique that tracks the time-averaged velocity-space structure of the energy density transfer rate between electromagnetic fields and pl…
Noise-Induced Magnetic Field Saturation in Kinetic Simulations
J. Juno, M. Swisdak, J. M. TenBarge +2
Monte Carlo methods are often employed to numerically integrate kinetic equations, such as the particle-in-cell method for the plasma kinetic equation, but these methods suffer fro…
Ion versus electron heating in compressively driven astrophysical gyrokinetic turbulence
Y. Kawazura, A. A. Schekochihin, M. Barnes +4
The partition of irreversible heating between ions and electrons in compressively driven (but subsonic) collisionless turbulence is investigated by means of nonlinear hybrid gyroki…
Major Scientific Challenges and Opportunities in Understanding Magnetic Reconnection and Related Explosive Phenomena throughout the Universe
H. Ji, A. Alt, S. Antiochos +97
This white paper summarizes major scientific challenges and opportunities in understanding magnetic reconnection and related explosive phenomena as a fundamental plasma process.
Dependence of Solar Wind Proton Temperature on the Polarisation Properties of Alfvénic Fluctuations at Ion-kinetic Scales
L. D. Woodham, R. T. Wicks, D. Verscharen +2
We use fluctuating magnetic helicity to investigate the polarisation properties of Alfvénic fluctuations at ion-kinetic scales in the solar wind as a function of , the ratio o…
Dynamo in weakly collisional nonmagnetized plasmas impeded by Landau damping of magnetic fields
István Pusztai, James Juno, Axel Brandenburg +4
We perform fully kinetic simulations of flows known to produce dynamo in magnetohydrodynamics (MHD), considering scenarios with low Reynolds number and high magnetic Prandtl number…
