Characterising arbitrary dark solitons in trapped one-dimensional Bose-Einstein condensates
H. A. J. Middleton-Spencer, N. G. Parker, L. Galantucci +1
We present a method to detect the presence and depth of dark solitons within repulsive one-dimensional harmonically trapped Bose-Einstein condensates. For a system with one soliton…
Dynamical Phase Diagram of Ultracold Josephson Junctions
K. Xhani, L. Galantucci, C. F. Barenghi +3
We provide a complete study of the phase diagram characterising the distinct dynamical regimes emerging in a three-dimensional Josephson junction in an ultracold quantum gas. Consi…
Turbulent, pinned superfluids in neutron stars and pulsar glitch recoveries
Brynmor Haskell, Danai Antonopoulou, Carlo Barenghi
Pulsar glitches offer an insight into the dynamics of superfluids in the high density interior of a neutron star. To model these phenomena, however, one needs to have an understand…
Classical and quantum vortex leapfrogging in two-dimensional channels
Luca Galantucci, Michele Sciacca, Nick G Parker +2
The leapfrogging of coaxial vortex rings is a famous effect which has been noticed since the times of Helmholtz. Recent advances in ultra-cold atomic gases show that the effect can…
Superfluid turbulence driven by cylindrically symmetric thermal counterflow
E. Rickinson, C. F. Barenghi, Y. A. Sergeev +1
We show by direct numerical simulations that the turbulence generated by steadily heating a long cylinder immersed in helium~II is strongly inhomogeneous and consists of a dense tu…
Intra-scales energy transfer during the evolution of turbulence in a trapped Bose-Einstein condensate
Arnol Daniel García-Orozco, Lucas Madeira, Luca Galantucci +2
In turbulence phenomena, including the quantum turbulence in superfluids, an energy flux flows from large to small length scales, composing a cascade of energy. A universal charact…
A new self-consistent approach of quantum turbulence in superfluid helium
Luca Galantucci, Andrew W. Baggaley, Carlo F. Barenghi +1
We present the Fully cOUpled loCAl model of sUperfLuid Turbulence (FOUCAULT) that describes the dynamics of finite temperature superfluids. The superfluid component is described by…
