Nonlinear Interactions in Spherically Polarized Alfvénic Turbulence
Trevor A. Bowen, Samuel T. Badman, Stuart D. Bale +8
Turbulent magnetic field fluctuations observed in the solar wind often maintain a constant magnitude condition accompanied by spherically polarized velocity fluctuations; these sig…
[Plasma 2020 Decadal] The Material Properties of Weakly Collisional, High-Beta Plasmas
M. W. Kunz, J. Squire, S. A. Balbus +14
This white paper, submitted for the Plasma 2020 Decadal Survey, concerns the physics of weakly collisional, high-beta plasmas -- plasmas in which the thermal pressure dominates ove…
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…
The Hamiltonian structure and Euler-Poincaré formulation of the Vlasov-Maxwell and gyrokinetic systems
J. Squire, H. Qin, W. M. Tang +1
We present a new variational principle for the gyrokinetic system, similar to the Maxwell-Vlasov action presented in Ref. 1. The variational principle is in the Eulerian frame and…
