Crossover from interaction to driven regimes in quantum vortex reconnections
Luca Galantucci, Andrew W. Baggaley, Nick G. Parker +1
Reconnections of coherent filamentary structures play a key role in the dynamics of fluids, redistributing energy and helicity among the length scales, triggering dissipative effec…
Inviscid diffusion of vorticity in low temperature superfluid helium
Em Rickinson, Nick G. Parker, Andrew W. Baggaley +1
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…
Diffusion of Quantum Vortices
Em Rickinson, Nick G. Parker, Andrew W. Baggaley +1
We determine the evolution of a cluster of quantum vortices initially placed at the centre of a larger vortex-free region. We find that the cluster spreads out spatially. This spre…
Mesoscale helicity distinguishes Vinen from Kolmogorov turbulence in helium II
L. Galantucci, C. F. Barenghi, N. G. Parker +1
Experiments and numerical simulations show that quantum turbulence exists in two distinct limiting regimes: Kolmogorov turbulence (which shares with classical turbulence the import…
Probing quasi-integrability of the Gross-Pitaevskii equation in a harmonic-oscillator potential
Thomas Bland, Nick G. Parker, Nick P. Proukakis +1
Previous simulations of the one-dimensional Gross-Pitaevskii equation (GPE) with repulsive nonlinearity and a harmonic-oscillator trapping potential hint towards the emergence of q…
