Long-range sound-mediated dark soliton interactions in trapped atomic condensates
A. J. Allen, D. P. Jackson, C. F. Barenghi +1
A long-range soliton interaction is discussed whereby two or more dark solitons interact in an inhomogeneous atomic condensate, modifying their respective dynamics via the exchange…
The saturation of decaying counterflow turbulence in helium II
Michele Sciacca, Yuri A. Sergeev, Carlo F. Barenghi +1
We are concerned with the problem of the decay of a tangle of quantized vortices in He II generated by a heat current. Direct application of Vinen's equation yields the temporal sc…
Turbulent superfluid profiles in a counterflow channel
L. Galantucci, C. F. Barenghi, M. Sciacca +2
We have developed a two-dimensional model of quantised vortices in helium II moving under the influence of applied normal fluid and superfluid in a counterflow channel. We predict…
The approach to vortex reconnection
Richard Tebbs, Anthony J. Youd, Carlo F. Barenghi
We present numerical solutions of the Gross--Pitaevskii equation corresponding to reconnecting vortex lines. We determine the separation of vortices as a function of time during th…
Spectrum of turbulent Kelvin-waves cascade in superfluid helium
Andrew W. Baggaley, Carlo F. Barenghi
To explain the observed decay of superfluid turbulence at very low temperature, it has been proposed that a cascade of Kelvin waves (analogous to the classical Kolmogorov cascade)…
Vortex length, vortex energy and fractal dimension of superfluid turbulence at very low temperature
David Jou, Maria Stella Mongiovi', Michele Sciacca +1
By assuming a self-similar structure for Kelvin waves along vortex loops with successive smaller scale features, we model the fractal dimension of a superfluid vortex tangle in the…
