| Abstract: | The magnetic electron drift vortex (MEDV) mode of unmagnetized nonuniform plasma has been investigated using Braginskii fluid equations. The nonlinear coupled equations of the perturbed magnetic field and the perturbed temperature are derived in the beginning. Following Stenflo's method, the nonlinear equations governing the evolution of the amplitude of the Lorentz-like mode are derived. The numerical investigation of such equations shows that orderly and chaotic structures appear in different regions of the parametric space. |
