Abstract Text:
Electron Magnetohydrodynamic Turbulence: Universal

The energy cascade of electron magnetohydrodynamic (EMHD)
turbulence is considered (Shivamoggi [1]). Several basic features
of the EMHD turbulent system are found to be universal which
seem to transcend the existence of the characteristic length scale (which is the electron skin depth) in the EMHD problem

equipartition spectrum,
Reynolds-number scaling of the dissipative microscales,
scaling of the probability distribution function (PDF) of the
electron-flow velocity (or magnetic field) gradient (even with
intermittency corrections),
dissipative anomaly,
critical exponent scaling.
