Theoretical investigation of the Hall effect in MHD turbulence

Abstract

The turbulence electromotive force in the Hall-MHD turbulence has been investigated based on two-scale direct-interaction approximation (TSDIA) which is a series of analytical treatments of inhomogeneous turbulence. In the present work the treatment of the propagator of the nonlinear interaction between velocity and magnetic fields in the sense of renormalized perturbation method. As a result a new term has been derived in the electromotive force which suggests that the aliment between velocity and magnetic fluctuations in small scale can cause effective electromotive force parallel to the mean magnetic field.[This abstract is not included in the PDF]
