Fractional Dynamics and Modulational Instability in Long-Range Heisenberg Chains
Laetitia Mbetkwe Youwa, Jean Pierre Nguenang, Paul André Paglan +3
We study the effective dynamics of ferromagnetic spin chains in presence of long-range interactions. We consider the Heisenberg Hamiltonian in one dimension for which the spins are…
Breaking of internal waves parametrically excited by ageostrophic anticyclonic instability
Yohei Onuki, Sylvain Joubaud, Thierry Dauxois
A gradient-wind balanced flow with an elliptic streamline parametrically excites internal inertia-gravity waves through ageostrophic anticyclonic instability (AAI). This study nume…
Three-dimensionality of the triadic resonance instability of a plane inertial wave
Daniel Odens Mora, Eduardo Monsalve, Maxime Brunet +2
We analyze theoretically and experimentally the triadic resonance instability (TRI) of a plane inertial wave in a rotating fluid. Building on the classical triadic interaction equa…
Vortex cluster arising from an axisymmetric inertial wave attractor
Samuel Boury, Ilias Sibgatullin, Evgeny Ermanyuk +5
We present an experimental study of the saturated non-linear dynamics of an inertial wave attractor in an axisymmetric geometrical setting. The experiments are carried out in a rot…
Simulating turbulent mixing caused by local instability of internal gravity waves
Y. Onuki, S. Joubaud, T. Dauxois
With the aim of assessing internal wave-driven mixing in the ocean, we develop a new technique for direct numerical simulations of stratified turbulence. Since the spatial scale of…
Succession of resonances to achieve internal wave turbulence
Géraldine Davis, Timothée Jamin, Julie Deleuze +2
We study experimentally the interaction of nonlinear internal waves in a stratified fluid confined in a trapezoidal tank. The set-up has been designed to produce internal wave turb…
