Maximum entropy states and coherent structures in magnetohydrodynamics

Abstract: "We review a recently developed model of coherent structures in two-dimensional magnetohydrodynamic turbulence. This model is based upon a constrained maximum entropy principle: Most probable states are determined as maximizers of entropy subject to constraints imposed by the conservation of energy, cross-helicity, and flux under the evolution of an ideal two-dimensional magnetofluid. Predictions of the model are compared with results of high-resolution numerical simulations of magnetofluid turbulence."
