Numerical investigation of the Kelvin-wave cascade in superfluid

A. W. Baggaley, J. Laurie

We numerically simulate weakly nonlinear Kelvin-wave interactions on the single periodic quantized vortex line in helium II using the vortex filament model with a tree algorithm. We show that for weakly nonlinear Kelvin-waves, we have excellent agreement to the L'vov-Nazarenko spectrum and clearly show deviation from the other theories. Additionally, we observe a transition into a critical balance state when forcing is increased.
