Magnetohydrodynamic fluctuations near thermal equilibrium

Abstract

A statistical equilibrium ensemble for a class of nonlinear, ideal, compressible magnetohydrodynamics models is constructed. If the departure from thermal equilibrium is due to helical magnetic-field configurations, then the magnetic-field fluctuation spectrum differs profoundly from that predicted by Landau's theory of fluid fluctuations which involves zero helicity. Some of the results of that theory however are recovered, as far as fluctuations of fluid-dynamical (nonmagnetic) variables are concerned, in the linear limit of our nonlinear theory. Comparisons are also made with related models of incompressible plasma turbulence.
