AB - We present results from a high-resolution and large-scale hybrid (fluid electrons and particle-in-cell protons) twodimensionalnumerical simulation of decaying turbulence. Two distinct spectral regions (separated by a smoothbreak at proton scales) develop with clear power-law scaling, each one occupying about a decade in wavenumbers.The simulation results simultaneously exhibit several properties of the observed solar wind fluctuations: spectralindices of the magnetic, kinetic, and residual energy spectra in the magnetohydrodynamic (MHD) inertial rangealong with a flattening of the electric field spectrum, an increase in magnetic compressibility, and a strong couplingof the cascade with the density and the parallel component of the magnetic fluctuations at sub-proton scales. Ourfindings support the interpretation that in the solar wind, large-scale MHD fluctuations naturally evolve beyondproton scales into a turbulent regime that is governed by the generalized Ohm’s law
