ABSTRACT NON-LINEAR DEVELOPMENT OF STREAMING INSTABILITIES IN MAGNETIC RECONNECTION
... Turbulence has been observed in the intense current layers that develop during magnetic reconnection in the Earth’s magnetosphere. Electron streaming is believed to be the source of this turbulence. Using kinetic theory and 3D particlein-cell simulations, we study the nonlinear development of strea ...
