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…

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…
