title: Numerical study of the magnetic electron drift vortex mode turbulence in a nonuniform magnetoplasma.
abstract: A simulation study of the magnetic electron drift vortex (MEDV) mode turbulence in a magnetoplasma in the presence of inhomogeneities in the plasma temperature and density, as well as in the external magnetic field, is presented. The study shows that the influence of the magnetic field inhomogeneity is to suppress streamerlike structures observed in previous simulation studies without background magnetic fields. The MEDV mode turbulence exhibits nonuniversal (non-Kolmogorov-type) spectra for different sets of the plasma parameters. In the presence of an inhomogeneous magnetic field, the spectrum changes to a 7/3 power law, which is flatter than without magnetic field gradients. The relevance of this work to laser-produced plasmas in the laboratory is briefly mentioned.
