Perpendicular ion heating in turbulence and reconnection: magnetic moment breaking by coherent fluctuations
Alfred Mallet, Kristopher G. Klein, Benjamin D. G. Chandran +2
We study the interaction of an ion with a fluctuation in the electromagnetic fields that is localized in both space and time. We study the scale-dependence of the interaction in bo…

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…
