Reproducible nucleation and control of stable quantum vortex rings in Bose-Einstein condensates
Giorgia Iori, Klejdja Xhani, Woo Jin Kwon +2
We propose and numerically validate an experimentally feasible on-demand protocol for the nucleation and manipulation of stable quantum vortex rings in trapped Bose-Einstein conden…
Experimental and theoretical evidence of universality in superfluid vortex reconnections
Piotr Z. Stasiak, Yiming Xing, Yousef Alihosseini +5
The minimum separation between reconnecting vortices in fluids and superfluids obeys a universal scaling law with respect to time. The pre-reconnection and the post-reconnection pr…
Strong Quantum Turbulence in Bose Einstein Condensates
H. A. J. Middleton-Spencer, A. D. G. Orozco, L. Galantucci +5
By combining experiments and numerical simulations which model the dynamics of shaken atomic Bose-Einstein condensates, we reveal the surprising nature of quantum turbulence in the…
Sound emission and annihilations in a programmable quantum vortex collider
W. J. Kwon, G. Del Pace, K. Xhani +5
In quantum fluids, the quantisation of circulation forbids the diffusion of a vortex swirling flow seen in classical viscous fluids. Yet, a quantum vortex accelerating in a superfl…
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…
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…
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…
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…
Quantum ferrofluid turbulence
T. Bland, G. W. Stagg, L. Galantucci +2
We study the elementary characteristics of turbulence in a quantum ferrofluid through the context of a dipolar Bose gas condensing from a highly non-equilibrium thermal state. Our…
Vortex reconnections and rebounds in trapped atomic Bose--Einstein condensates
Simone Serafini, Luca Galantucci, Elena Iseni +6
Reconnections and interactions of filamentary coherent structures play a fundamental role in the dynamics of fluids, plasmas and nematic liquid crystals. In fluids, vortex reconnec…
