MMS Observations of Kinetic Alfv'en Wave Turbulence and Steep Kinetic-Range Spectra in the Outer Plasma Sheet Boundary Layer
The episode discusses a paper by Chettri et al. regarding kinetic Alfvén wave turbulence and steep kinetic-range spectra in the outer plasma sheet boundary layer, observed by MMS. Hosts discuss how this evidence requires moving beyond standard models to create multi-scale, self-correcting computational simulations that can handle anisotropic physics and automatically switch between fluid and kinetic treatments.
