  author={Victor S L’vov and Sergey V Nazarenko},
  journal={Physical Review B},
We comment on the paper by Sonin [Phys. Rev. B 85, 104516 (2012)] with most statements of which we disagree. We use this option to shed light on some important issues of a theory of Kelvin-wave turbulence, touched on in Sonin's paper, in particular, on the relation between the Vinen spectrum of strong and the L'vov-Nazarenko spectrum of weak turbulence of Kelvin waves. We also discuss the role of explicit calculation of the Kelvin-wave interaction Hamiltonian and ``symmetry arguments'' that… 

Kelvin waves and the decay of quantum superfluid turbulence

intervortex distance � . These excitations cascade down to the resolution scale �ξ which in our simulations is of the order �ξ ∼ �/ 100. At this scale, the Kelvin waves are numerically damped by a

Scaling laws of wave-cascading superfluid turbulence

Phenomenological model is constructed for superfluid turbulence for two distinct energy cascade scenarios, sound wave cascade and critically-balanced Kelvin wave cascade, using the method for

Velocity spectra of quantum turbulence: experiments, numerics and models

Superfluid Turbulence is unusual and presents a challenge to fluid dynamicists because it consists of two coupled, inter penetrating turbulent fluids: the first is inviscid with quantised vorticity,

Experimental, numerical, and analytical velocity spectra in turbulent quantum fluid

Experimental, numerical, and theoretical results are presented that explain the similarities of the observed spectra of the superfluid turbulent velocity at sufficiently large length scales and illustrate the limits of the present understanding of superfluid turbulence at smaller scales.

Turbulent velocity spectra in a quantum fluid : experiments , numerics and theory

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and

Energy and vorticity spectra in turbulent superfluidHe4fromT=0toTλ

We discuss the energy and vorticity spectra of turbulent superfluid $^{4}\mathrm{He}$ in the entire temperature range from $T=0$ up to the phase transition ``$\ensuremath{\lambda}$ point,''
