Capillary freak waves in He-II as a manifestation of discrete wave turbulent regime

Accordingly, three wave turbulent regimes can be singled out - \emph{kinetic} (described by wave kinetic equations and KZ-spectra, in random phase approximation, \cite{ZLF92}); \emph{discrete} (described by a few dynamical systems, with coherent phases corresponding to resonance conditions, \cite{K09b}) and \emph{mesoscopic} (where kinetic and discrete evolution of the wave field coexist, \cite{zak4}).We present an explanation of freak waves appearance in capillary waves in He-II, \cite{ABKL09}, as a manifestation of discrete wave turbulent regime. Implications of these results for other wave systems are briefly discussed.},

Accordingly, three wave turbulent regimes are singled out: \emph{kinetic}, described by wave kinetic equations and power energy spectra; \emph{discrete}, characterized by resonance clustering; and \emph{mesoscopic},where both types of wave field time evolution coexist. In this paper we study integrable dynamics of resonance clusters appearing in discrete and mesoscopic wave turbulent regimes. Usinga novel method based on the notion of dynamical invariant we establish that some of the frequently met clusters areintegrable in quadratures for arbitrary initial conditions and some others -- only for particular initial conditions. Wealso identify chaotic behaviour in some cases. Physical implications of the results obtained are discussed.},

Turbulence of capillary waves revisited

title = {{Turbulence of capillary waves revisited}},
language = {english},
abstract = {Kinetic regime of capillary wave turbulence is classically regarded in terms of three-wave interactions with the exponent of power energy spectrum being $\nu=-7/4$ (two-dimensional case). We show that a number of assumptions necessary for this regime to occur can not be fulfilled. Four-wave interactions of capillary waves should be taken into account instead, which leads to exponents $\nu=-13/6$ and $\nu=-3/2$ for one- and two-dimensional wavevectors correspondingly. It follows that for general dispersion functions of decay type, three-wave kinetic regime need not prevail and higher order resonances may play a major role.},

Inthe generic case, the set of nonlinear resonances consists ofindependent clusters of resonantly interacting modes, described by afew low-dimensional dynamical systems. We formulate and prove a newtheorem on integrability which allows us to show that mostfrequently met clusters are described by integrable dynamicalsystems. We argue that construction of clusters can be used as thebase for the Clipping method, substantially more effective for thesesystems than the Galerkin method. The results can be used directlyfor systems with cubic Hamiltonian.},

This phase combination iscalled dynamical phase, its evolution is studied numerically, bothfor a triad and for a cluster formed by two connected triads. Weshow that dynamical phases, usually regarded as equal to zero orconstants, play substantial role in the dynamics of the clusters.Indeed, effects are (i) to diminish the period of energy exchange$\tau$ within a cluster by 20$\%$ and more; (ii) to diminish, attime scale $\tau$, the variability of wave energies by 25$\%$ andmore; (iii) to generate a new time scale, $T >> \tau$, in which weobserve considerable energy exchange within a cluster, as well as anincreasing in the variability of modes' energies. These findings can be applied, for example, tothe control of energy input, exchange and output in Tokamaks; forexplanation of some experimental results, etc.},

Among them, new integrable dynamical systems havebeen found that can be used for explaining numerical andlaboratory results. The aim of this paper is to give a briefoverview of our current knowledge about nonlinear resonances amongwater waves, and formulate three most important open problems at the end.},

Clusters with integrable and chaotic dynamics co-exist in different sub-spaces of the $\mathbf{k}$-space. NR-diagrams are introduced, a graphical representation of an arbitrary resonance cluster allowing to reconstruct uniquely dynamical system describing the cluster. DWT is shown to be a novel research field in nonlinear science, with its own methods, achievements and application areas.},

These clusterscan be formed by two types of quartets: (1) {\it angle-resonances} which cannot directly cascade energy but which canredistribute it among the initially excited modes and (2) {\itscale-resonances} which are much more rare but which are the onlyones that can transfer energy between different scales. We find suchresonant quartets and their clusters numerically on the set of 1000x 1000 modes, classify and quantify them and discuss consequences ofthe obtained cluster structure for the wavefield evolution. Finitebox effects and associated resonant interaction among discrete wavemodes appear to be important in most numerical and laboratoryexperiments on the deep water gravity waves, and our work is aimedat aiding the interpretation of the experimental and numerical data.},
