Sign-Indefinite Helicity and the Structure of Weak Turbulence in Inertial and Non-Hermitian Waves
Shahaf Aharony Shapira, Michal Shavit
We investigate how sign-indefinite quadratic invariants shape turbulent cascades in incompressible flows with broken time-reversal symmetry, where the dynamics supports strongly an…
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…
The role of sign indefinite invariants in shaping turbulent cascades
Michal Shavit, Oliver Bühler, Jalal Shatah
We highlight a non-canonical yet natural choice of variables for an efficient derivation of a kinetic equation for the energy density in non-isotropic systems, including internal g…
Kinetic equation for weak interaction of directional internal waves
Michal Shavit, Oliver Bühler, Jalal Shatah
Starting from the two-dimensional Boussinesq equation without rotation, we derive a kinetic equation for weak interaction of internal waves using non-canonical variables. We follow…
Second harmonic generation as a minimal model of turbulence
N. Vladimirova, M. Shavit, S. Belan +1
When two resonantly interacting modes are in contact with a thermostat, their statistics is exactly Gaussian and the modes are statistically independent despite strong interaction.…
Fibonacci turbulence
Natalia Vladimirova, Michal Shavit, Gregory Falkovich
Never is the difference between thermal equilibrium and turbulence so dramatic, as when a quadratic invariant makes the equilibrium statistics exactly Gaussian with independently f…
Singular measures and information capacity of turbulent cascades
Gregory Falkovich, Michal Shavit
Is there really such a thing as weak turbulence? Here we analyze turbulence of weakly interacting waves using the tools of information theory. It offers a unique perspective for co…
Freely flowing currents and electric field expulsion in viscous electronics
Michal Shavit, Andrey Shytov, Gregory Falkovich
Electronic fluids bring into hydrodynamics a new setting: equipotential flow sources embedded inside the fluid. Here we show that nonlocal relation between current and electric fie…
Neutrinoless double-beta decay with massive scalar emission
Kfir Blum, Yosef Nir, Michal Shavit
Searches for neutrino-less double-beta decay () place an important constraint on models where light fields beyond the Standard Model participate in the neutrino mass mechan…
