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…

Gravitational wave turbulence: a multiple time scale approach for quartic wave interactions
Benoît Gay, Sébastien Galtier
Wave turbulence is by nature a multiple time scale problem for which there is a natural asymptotic closure. The main result of this analytical theory is the kinetic equation that d…
