Can Hall Magnetohydrodynamics Explain Plasma Turbulence at Sub-ion Scales?

Can Hall Magnetohydrodynamics Explain Plasma Turbulence at Sub-ion Scales?

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 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 …
