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…
Compressible magnetohydrodynamic turbulence in the Earth's magnetosheath: estimation of the energy cascade rate using in situ spacecraft data
Lina Hadid, Fouad Sahraoui, Sebastien Galtier +1
The first estimation of the energy cascade rate of magnetosheath turbulence is obtained using the CLUSTER and THEMIS spacecraft data and an exact law of compressible isot…
Exact law for homogeneous compressible Hall magnetohydrodynamics turbulence
Nahuel Andrés, Sébastien Galtier, Fouad Sahraoui
We derive the exact law for three-dimensional (3D) homogeneous compressible isothermal Hall magnetohydrodynamics (CHMHD) turbulence, without the assumption of isotropy. The Hall cu…
Turbulence of Weak Gravitational Waves in the Early Universe
S. Galtier, S. V. Nazarenko
We study the statistical properties of an ensemble of weak gravitational waves interacting nonlinearly in a flat space-time. We show that the resonant three-wave interactions are a…
