The 17/5 spectrum of the Kelvin-wave cascade
Evgeny Kozik, Boris Svistunov
Direct numeric simulation of the Biot-Savart equation readily resolves the 17/5 spectrum of the Kelvin-wave cascade from the 11/3 spectrum of the non-local (in the wavenumber space…
Geometric Symmetries in Superfluid Vortex Dynamics
Evgeny Kozik, Boris Svistunov
Dynamics of quantized vortex lines in a superfluid feature symmetries associated with the geometric character of the complex-valued field, , describing the instant…
Scanning Superfluid-Turbulence Cascade by Its Low-Temperature Cutoff
Evgeny Kozik, Boris Svistunov
On the basis of recently proposed scenario of the transformation of the Kolmogorov cascade into the Kelvin-wave cascade, we develop a theory of low-temperature cutoff. The theory p…
Kolmogorov and Kelvin-Wave Cascades of Superfluid Turbulence at T=0: What is in Between?
Evgeny Kozik, Boris Svistunov
As long as vorticity quantization remains irrelevant for the long-wave physics, superfluid turbulence supports a regime macroscopically identical to the Kolmogorov cascade of a nor…
Vortex--Phonon Interaction
Evgeny Kozik, Boris Svistunov
Kelvin waves (kelvons)--helical waves on quantized vortex lines--are the normal modes of vortices in a superfluid. At zero temperature, the only dissipative channel of vortex dynam…
Scale Separation Scheme for Simulating Superfluid Turbulence: Kelvin-Wave Cascade
Evgeny Kozik, Boris Svistunov
A Kolmogorov-type cascade of Kelvin waves--the distortion waves on vortex lines--plays a key part in the relaxation of superfluid turbulence at low temperatures. We propose an effi…
