Wave turbulence theory of odd fluids and solids: kinetic equations and solutions
Xander M. de Wit, Léo Touzo, Sébastien Galtier +3
The theory of wave turbulence describes the properties of physical systems composed of a set of weak-amplitude random waves interacting nonlinearly. Here, we study odd wave turbule…
Odd wave turbulence
Xander M. de Wit, Léo Touzo, Sébastien Galtier +3
Wave turbulence describes the statistical dynamics of weakly interacting waves in out-of-equilibrium systems. These systems are out of equilibrium because forcing and dissipation o…
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…
Towards Gravitational Wave Turbulence within the Hadad-Zakharov metric
Benoît Gay, Eugeny Babichev, Sébastien Galtier +1
The theory of gravitational wave turbulence describes the long-term statistical behaviour of a set of weakly nonlinear interacting waves. In this paper, we aim to study aspects of…
Asymmetric dual cascade in gravitational wave turbulence
Benoît Gay, Sébastien Galtier
We numerically simulate, in both the forced and decay regimes, a fourth-order nonlinear diffusion equation derived from the kinetic equation of gravitational wave turbulence in the…
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…
