Monofractality in the solar wind at electron scales: insights from KAW turbulence
Vincent David, Sébastien Galtier, Romain Meyrand
The breakdown of scale invariance in turbulent flows, known as multifractal scaling, is considered a cornerstone of turbulence. In solar wind turbulence, a monofractal behavior can…
On exact laws in incompressible Hall magnetohydrodynamic turbulence
Renaud Ferrand, Sébastien Galtier, Fouad Sahraoui +3
A comparison is made between several existing exact laws in incompressible Hall magnetohydrodynamic (IHMHD) turbulence in order to show their equivalence, despite stemming from dif…
Coexistence of weak and strong wave turbulence in incompressible Hall magnetohydrodynamics
Romain Meyrand, Khurom H. Kiyani, Ozgur D. Gurcan +1
We report a numerical investigation of three dimensional, incompressible, Hall magnetohydrodynamic turbulence with a relatively strong mean magnetic field. Using helicity decomposi…
Direct Evidence of the Transition from Weak to Strong MHD Turbulence
Romain Meyrand, Sebastien Galtier, Khurom H. Kiyani
One of the most important predictions in magnetohydrodynamics (MHD) is that in the presence of a uniform magnetic field a transition from weak to strong wave turbu…
Intermittency in Weak Magnetohydrodynamic Turbulence
Romain Meyrand, Khurom H. Kiyani, Sebastien Galtier
Intermittency is investigated using decaying direct numerical simulations of incompressible weak magnetohydrodynamic turbulence with a strong uniform magnetic field and…
Entanglement of helicity and energy in kinetic Alfven wave/whistler turbulence
S. Galtier, R. Meyrand
The role of magnetic helicity is investigated in kinetic Alfvén wave and oblique whistler turbulence in presence of a relatively intense external magnetic field $b_0 {\bf e_\parall…
A Universal Law for Solar-Wind Turbulence at Electron Scales
R. Meyrand, S. Galtier
The interplanetary magnetic fluctuation spectrum obeys a Kolmogorovian power law at scales above the proton inertial length and gyroradius which is well regarded as an inertial ran…
