Can Hall Magnetohydrodynamics Explain Plasma Turbulence at Sub-ion Scales?
Original language description
We investigate the properties of plasma turbulence by means of two-dimensional Hall-magnetohydrodynamic (HMHD) and hybrid particle-in-cell (HPIC) numerical simulations. We find that the HMHD simulations exhibit spectral properties that are in most cases in agreement with the results of the HPIC simulations and with solar wind observations. The energy spectra of magnetic fluctuations exhibit a double power law with spectral index -5/3 at MHD scales and -3 at kinetic scales, while for velocity fluctuations the spectral index is -3/2 at MHD scales.
