Torsional Oscillations of a Rotating Column of He-B
Karen L. Henderson, Carlo F. Barenghi
We have analysed the axisymmetric and non-axisymmetric modes of a continuum of vortices in a rotating superfluid. We have investigated how changing the temperature affects the grow…
Decay of quantised vorticity by sound emission
C. F. Barenghi, N. G. Parker, N. P. Proukakis +1
It is thought that in a quantum fluid sound generation is the ultimate sink of turbulent kinetic energy in the absence of any other dissipation mechanism near absolute zero. We sho…
Parametric Driving of Dark Solitons in Atomic Bose-Einstein Condensates
N. P. Proukakis, N. G. Parker, C. F. Barenghi +1
A dark soliton oscillating in an elongated harmonically-confined atomic Bose-Einstein condensate continuously exchanges energy with the sound field. Periodic optical `paddles' are…
Vortex waves and the onset of turbulence in He-B
K. L. Henderson, C. F. Barenghi
In a recent experiment Finne et al. discovered an intrinsic condition for the onset of quantum turbulence in He-B, that q=alpha/(1-alpha')<1, where alpha and alpha' are mutual…
Vortex nucleation by collapsing bubbles in Bose-Einstein condensates
Natalia G. Berloff, Carlo F. Barenghi
The nucleation of vortex rings accompanies the collapse of ultrasound bubbles in superfluids. Using the Gross-Pitaevskii equation for a uniform condensate we elucidate the various…
