On a wave kinetic equation with resonance broadening in oceanography and atmospheric sciences
Young Ho Kim, Yuri V. Lvov, Leslie M. Smith +1
In this work, we study a three-wave kinetic equation with resonance broadening arising from the theory of stratified ocean flows. Unlike Gamba-Smith-Tran(On the wave turbulence the…
Spectral Transfers of Sign-Definite Invariants in Wave Turbulence
Nicholas R. Salvatore, Giovanni Dematteis, Yuri V. Lvov
We consider the spectral transfers of sign-definite invariants in general wave turbulence systems equipped with a wave kinetic equation. We develop a formalism to investigate and t…
Anomalous correlators, negative frequencies and non-phase-invariant Hamiltonians in random waves
Alberto Villois, Giovanni Dematteis, Yuri V. Lvov +2
We investigate a generic non-phase invariant Hamiltonian model that governs the dynamics of nonlinear dispersive waves. We give evidence that initial data characterized by random p…
Interacting internal waves explain global patterns of interior ocean mixing
Giovanni Dematteis, Arnaud Le Boyer, Friederike Pollmann +4
Across the stable density stratification of the abyssal ocean, deep dense water is slowly propelled upward by sustained, though irregular, turbulent mixing. The resulting mean upwe…
Exact discrete resonances in the Fermi-Pasta-Ulam-Tsingou system
Miguel D. Bustamante, Kevin Hutchinson, Yuri V. Lvov +1
In systems of N coupled anharmonic oscillators, exact resonant interactions play an important role in the energy exchange between normal modes. In the weakly nonlinear regime, thos…
Wave turbulence revisited: Where does the energy flow?
L. V. Abdurakhimov, I. A. Remizov, A. A. Levchenko +2
Turbulence in a system of nonlinearly interacting waves is referred to as wave turbulence. It has been known since seminal work by Kolmogorov, that turbulent dynamics is controlled…
