Reaction-diffusion models of invasive tree pest spread: quantifying the expansion of oak processionary moth in the UK
Jamie P. McKeown, Laura E. Wadkin, Nick G. Parker +2
UK woodlands, forests, and urban treescapes are under threat from invasive species, exacerbated by climate change, trade, and transport. Invasive tree pests debilitate their host a…
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…
Inverse energy transfer in three-dimensional quantum vortex flows
Piotr Z. Stasiak, Andrew Baggaley, Carlo. F. Barenghi +2
Vortex reconnections play a fundamental role in fluids.They increase the complexity of flow and develop small-scale motions.In this work, we report that in superfluids, they can al…
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…
Vortex Avalanches and Collective Motion in Neutron Stars
I-Kang Liu, Andrew W. Baggaley, Carlo F. Barenghi +1
We simulate the dynamics of about 600 quantum vortices in a spinning-down cylindrical container using a Gross--Pitaevskii model. For the first time, we find convincing spatial-temp…
