Towards Synthetic Magnetic Turbulence with Coherent Structures (2401.10573v3)
Published 19 Jan 2024 in physics.space-ph, astro-ph.HE, and physics.plasm-ph
Abstract: Synthetic turbulence is a relevant tool to study complex astrophysical and space plasma environments inaccessible by direct simulation. However, conventional models lack intermittent coherent structures, which are essential in realistic turbulence. We present a novel method, featuring coherent structures, conditional structure function scaling and fieldline curvature statistics comparable to magnetohydrodynamic turbulence. Enhanced transport of charged particles is investigated as well. This method presents significant progress towards physically faithful synthetic turbulence.
