Sign-Indefinite Helicity and the Structure of Weak Turbulence in Inertial and Non-Hermitian Waves
Shahaf Aharony Shapira, Michal Shavit
The paper studies how sign‑indefinite helicity influences energy cascades in rotating and odd‑viscous incompressible flows by deriving and solving a weak‑turbulence kinetic equatio…
Wave turbulence of inertia--gravity waves: a theory for the oceanic spectrum
Michal Shavit, Oliver Bühler, Jalal Shatah
We present a derivation using kinetic wave theory of the two-dimensional empirical Garrett--Munk spectrum for ocean internal waves, valid at all frequencies including near-inertial…
Space-time resonances in the spatiotemporal spectrum of nonlinear dispersive waves
Michal Shavit, Fabio Pusateri, Zhou Zhang +4
In weakly nonlinear dispersive wave systems, long-time dynamics are typically governed by time resonances, where wave phases evolve coherently due to exact frequency matching. Rece…
2D Internal Gravity Wave Turbulence
Vincent Labarre, Michal Shavit
Using weak wave turbulence theory analysis, we distinguish three main regimes for 2D stratified fluids in the dimensionless parameter space defined by the Froude number and the Rey…
Turbulent spectrum of 2D internal gravity waves
Michal Shavit, Oliver Bühler, Jalal Shatah
We find the turbulent energy spectrum of weakly interacting 2D internal gravity waves using the full, non-hydrostatic dispersion relation. This spectrum is an exact solution of a r…
