Scale-Dependent Dynamic Alignment in MHD Turbulence: Insights into Intermittency, Compressibility, and Imbalance Effects
Nikos Sioulas, Marco Velli, Alfred Mallet +7
Scale-Dependent Dynamic Alignment (SDDA) in Elsässer field fluctuations is theorized to suppress nonlinearities and modulate the energy spectrum. Limited empirical evidence exists…
Higher-Order Analysis of Three-Dimensional Anisotropy in Imbalanced Alfvénic Turbulence
Nikos Sioulas, Themistocles Zikopoulos, Chen Shi +10
We analyze in-situ observations of imbalanced solar wind turbulence to evaluate MHD turbulence models grounded in "Critical Balance" (CB) and "Scale-Dependent Dynamic Alignment" (S…
[Plasma 2020 Decadal] Disentangling the Spatiotemporal Structure of Turbulence Using Multi-Spacecraft Data
J. M. TenBarge, O. Alexandrova, S. Boldyrev +26
This white paper submitted for 2020 Decadal Assessment of Plasma Science concerns the importance of multi-spacecraft missions to address fundamental questions concerning plasma tur…
Finite-Larmor-radius equilibrium and currents of the Earth's flank magnetopause
S. S. Cerri
We consider the one-dimensional equilibrium problem of a shear-flow boundary layer within an "extended Hall-MHD" (eHMHD) model of plasma that retains first-order finite Larmor radi…
Magnetic reconnection as a driver for a sub-ion scale cascade in plasma turbulence
L. Franci, S. S. Cerri, F. Califano +6
A new path for the generation of a sub-ion scale cascade in collisionless plasma turbulence, triggered by magnetic reconnection, is uncovered by means of high-resolution two-dimens…
Pressure anisotropy generation in a magnetized plasma configuration with a shear flow velocity
S. De Camillis, S. S. Cerri, F. Califano +1
The nonlinear evolution of the Kelvin Helmholtz instability in a magnetized plasma with a perpendicular flow close to, or in, the supermagnetosonic regime can produce a significant…
Nonlinear evolution of the magnetized Kelvin-Helmholtz instability: from fluid to kinetic modeling
P. Henri, S. S. Cerri, F. Califano +11
The nonlinear evolution of collisionless plasmas is typically a multi-scale process where the energy is injected at large, fluid scales and dissipated at small, kinetic scales. Acc…
