  journal={Physical Review B},
The small-scale energy-transfer mechanism in zero-temperature superfluid turbulence of helium-4 is still a widely debated topic. Currently, the main hypothesis is that weakly nonlinear interacting Kelvin waves (KWs) transfer energy to sufficiently small scales such that energy is dissipated as heat via phonon excitations. Theoretically, there are at least two proposed theories for Kelvin-wave interactions. We perform the most comprehensive numerical simulation of weakly nonlinear interacting…

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
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
Kolmogorov and Kelvin wave cascades in a generalized model for quantum turbulence
We performed numerical simulations of decaying quantum turbulence by using a generalized Gross-Pitaevskii equation that includes a beyond mean field correction and a nonlocal interaction potential.
Amplitude of Waves in the Kelvin-Wave Cascade
Development of experimental techniques to study superfluid dynamics, in particular, application of nanomechanical oscillators to drive vortex lines, enables potential observation of the Kelvin-wave
Comment on “Amplitude of Waves in the Kelvin-Wave Cascade” (JETP Letters 111, 389 (2020))
In the recently published preprint arXiv:200.02610 Eltsov and L'vov calculated the amplitudes of waves in the Kelvin-wave cascades. This returns us to the rather old, but still unresolved dispute on
Isotropic Turbulence with Coupled Microstructures. II: Quantum Turbulence
This chapter is devoted to Quantum turbulence in superfluid helium and Bose-Einstein condensates. Basic equations and theories related to the Gross-Pitaevski equation, the vortex filament model and
Inviscid diffusion of vorticity in low-temperature superfluid helium
We numerically study the spatial spreading of quantized vortex lines in low temperature liquid helium. The vortex lines, initially concentrated in a small region, diffuse into the surrounding
A Note on the Propagation of Quantized Vortex Rings Through a Quantum Turbulence Tangle: Energy Transport or Energy Dissipation?
We investigate quantum vortex ring dynamics at scales smaller than the inter-vortex spacing in quantum turbulence. Through geometrical arguments and high-resolution numerical simulations, we examine
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.
Coarse-grained pressure dynamics in superfluid turbulence
Quantum mechanics places significant restrictions on the hydrodynamics of superfluid flows. Despite this it has been observed that turbulence in superfluids can, in a statistical sense, share many of


Wave Turbulence Formalism
In this Chapter, the main mathematical derivation of the weak Wave Turbulence closure is presented. This includes formulating the nonlinear wave equation in Fourier space using the interaction
