Dynamics of fast magnetosonic wave turbulence
Nicolás Pablo Müller, Sébastien Galtier
Fast magnetosonic waves are among the fundamental oscillation modes of astrophysical plasmas. To study their dynamics, we carry out numerical simulations of the wave turbulence kin…
Impact of pressure anisotropy on the cascade rate of Hall-MHD turbulence with biadiabatic ions
Pauline A. Simon, Fouad Sahraoui, Sébastien Galtier +3
The impact of ion pressure anisotropy on the energy cascade rate of Hall-MHD turbulence with biadiabatic ions and isothermal electrons is evaluated in three-dimensional direct nume…
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…
Fast magneto-acoustic wave turbulence and the Iroshnikov-Kraichnan spectrum
Sebastien Galtier
An analytical theory of wave turbulence is developed for pure compressible magnetohydrodynamics in the small limit. In contrast to previous works where the multiple scale metho…

Vincent David, Sébastien Galtier
A wave turbulence theory is developed for inertial electron magnetohydrodynamics (IEMHD) in the presence of a relatively strong and uniform external magnetic field $\boldsymbol{B_0…
An in-depth numerical study of exact laws for compressible Hall magnetohydrodynamic turbulence
R. Ferrand, F. Sahraoui, S. Galtier +3
Various exact laws governing compressible magnetohydrodynamic (MHD) and Hall-MHD (CHMHD) turbulence have been derived in recent years. Other than their fundamental theoretical inte…
The incompressible energy cascade rate in anisotropic solar wind turbulence
N. Andrés, F. Sahraoui, Huang +2
Context. The presence of a magnetic guide field induces several types of anisotropy in solar wind turbulence. The energy cascade rate between scales in the inertial range depends s…

R. Ferrand, F. Sahraoui, D. Laveder +3
Using an exact law for incompressible Hall magnetohydrodynamics (HMHD) turbulence, the energy cascade rate is computed from three-dimensional HMHD-CGL (bi-adiabatic ions and isothe…
Proof of the zeroth law of turbulence in one-dimensional compressible magnetohydrodynamics and shock heating
Vincent David, Sébastien Galtier
The zeroth law is one of the oldest conjecture in turbulence that is still unproven. Here, we consider weak solutions of one-dimensional compressible magnetohydrodynamics and demon…

Nahuel Andrés, Sebastien Galtier, Fouad Sahraoui
We derive exact scaling laws for a three-dimensional incompressible helical two-fluid plasma, without the assumption of isotropy. For each ideal invariant of the two-fluid model, i…
