On the Wave Kinetic Equation in the presence of forcing and dissipation
Davide Maestrini, Daniele Noto, Giovanni Dematteis +1
The wave kinetic equation has become an important tool in different fields of physics. In particular, for surface gravity waves, it is the backbone of wave forecasting models. Its…
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…
Wave Turbulence and thermalization in one-dimensional chains
Miguel Onorato, Yuri V. Lvov, Giovanni Dematteis +1
One-dimensional chains are used as a fundamental model of condensed matter, and have constituted the starting point for key developments in nonlinear physics and complex systems. T…
Derivation of the Four-Wave Kinetic Equation in Action-Angle Variables
Miguel Onorato, Giovanni Dematteis
Starting from the action-angle variables and using a standard asymptotic expansion, here we present a new derivation of the Wave Kinetic Equation for resonant process of the type $…
