Quantum turbulent velocity statistics and quasiclassical limit
A. W. Baggaley, C. F. Barenghi
Two research groups have measured turbulent velocity statistics in superfluid helium using different techniques. The results were in conflict: one experiment revealed Gaussian dist…
Vortex knots in a Bose-Einstein condensate
Davide Proment, Miguel Onorato, Carlo F. Barenghi
We present a method for numerically building a vortex knot state in the superfluid wave-function of a Bose-Einstein condensate. We integrate in time the governing Gross-Pitaevskii…
Coherent vortex structures in quantum turbulence
Andrew W. Baggaley, Carlo F. Barenghi, Anvar Shukurov +1
This report addresses an important question discussed by the quantum turbulence community during the last decade: do quantized vortices form, in zero-temperature superfluids, coher…
Tree method for quantum vortex dynamics
Andrew W. Baggaley, Carlo F. Barenghi
We present a numerical method to compute the evolution of vortex filaments in superfluid helium. The method is based on a tree algorithm which considerably speeds up the calculatio…
Coherent cross-talk and parametric driving of matter-wave vortices
N. G. Parker, A. J. Allen, C. F. Barenghi +1
We show that the interaction between vortices and sound waves in atomic Bose-Einstein condensates can be elucidated in a double-well trap: with one vortex in each well, the sound e…
Shell model of superfluid turbulence
D. H. Wacks, C. F. Barenghi
Superfluid helium consists of two inter-penetrating fluids, a viscous normal fluid and an inviscid superfluid, coupled by a mutual friction. We develop a two-fluid shell model to s…
