Topological interactions in vortex-wave collisions in Bose-Einstein condensates
Vebjørn Øvereng, Andrew Baggaley, Luiza Angheluta
We study vortex-vortex and vortex-wave collisions in two-dimensional weakly interacting Bose-Einstein condensates, processes that play a central role in decaying quantum turbulence…
Out of Equilibrium Behaviour of Quantum Vortices: A Comparison of Point Vortex Dynamics and Fokker-Planck Evolution
R. J. Tattersall, A. W. Baggaley, T. P. Billam
An out of equilibrium two-dimensional superfluid relaxes towards equilibrium via a process of coarsening, driven by the annihilation of vortices with antivortices. Here we present…
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…
Crow instability of vortex lines in dipolar superfluids
Srivatsa B. Prasad, Nick G. Parker, Andrew W. Baggaley
In classical inviscid fluids, antiparallel vortices perturbed by Kelvin waves exhibit the Crow instability, where the mutual interaction of the Kelvin modes renders them dynamicall…
Vortex pair dynamics in three-dimensional homogeneous dipolar superfluids
Srivatsa B. Prasad, Nick G. Parker, Andrew W. Baggaley
The static and dynamic properties of vortices in dipolar Bose-Einstein condensates (dBECs) can be considerably modified relative to their nondipolar counterparts by the anisotropic…
Vortex depinning in a two-dimensional superfluid
I-Kang Liu, Srivatsa B. Prasad, Andrew W. Baggaley +2
We employ the Gross--Pitaevskii theory to model a quantized vortex depinning from a small obstacle in a two-dimensional superfluid due to an imposed background superfluid flow. We…
