Abstract [en]

Asimulation study of dynamical evolution of nonlinearly interacting two-dimensional magneticelectron drift vortex (MEDV) modes in a nonuniform plasma ispresented. Depending on the equilibrium density and temperature gradients, thesystem can either be stable or unstable. The unstable systemreveals spontaneous generation of magnetic fields from noise level, andlarge-scale magnetic field structures are formed. When the system islinearly stable, one encounters MEDV mode turbulence in which thereis a competition between zonons (zonal flows) and streamers. Forlarge MEDV mode amplitudes, one encounters the formation of localizedand small-scale magnetic vortices and vortex pairs with scale sizesof the order of the electron skin depth. The MEDVturbulence exhibits nonuniversal (non-Kolmogorov-type) spectra for different sets of plasmaparameters. The relevance of this work to laboratory and cosmicplasmas is briefly mentioned.
