Conformal Models of Magnetohydrodynamic Turbulence

Abstract

Following the previous work of Ferretti and Yang on the role of magnetic fields in the theory of conformal turbulence, we show that non-unitary minimal model solutions to 2-dimensional magnetohydrodynamics (MHD) obtained by dimensional reduction from 3-dimensions exist under different (and more restrictive) conditions. From a 3-dimensional point of view, these conditions are equivalent to perpendicular flow, in which the magnetic and velocity fields are orthogonal. We also extend the analysis to the finite conductivity case and present some approximate solutions, whose connection to the exact ones of the infinite conductivity case is also discussed.
