Finite Larmor Radius Effects and Quantum Chaos
Résumé
Informed by insights from quantum chaos theory, three approaches for estimating finite-Larmor-radius (FLR) stabilization of ideal magnetohydrodynamic (MHD) instabilities are discussed: phase space criteria based on the Weyl formula, ``pseudo-FLR'' modifications of MHD to suppress large perpendicular wavenumbers, and inclusion of drift corrections to the dispersion relation.
