Method Description: The data set corresponds to the figures in the associated publication, which were the results of numerical simulations. Data for each of the figures are clearly labelled. Full details of how the data was generated are given in the associated publication. Files included: fig1.mat - MATLAB data file containing the AFM image used to produce FIG. 1. fig2-a.fig, fig2-b.fig, fig2-c.fig, fig2-de.fig - MATLAB figure files containing snapshots of the wavefunction density with v=0.6c at t/\tau=20,30,100,1220. fig3.csv - CSV data file containing the data used to produce FIG. 3. This includes the Average vortex line length (L) as a function of height (z) and time (t) for the 3 cases v=0.3c, v=0.6c, and v=0.9c. fig4-a.fig,fig4-b.fig,fig4-c.fig,fig4-d.fig - MATLAB figure files containing snapshots of the wavefunction density with v=0.6c at t/\tau=730,740,750,770. fig5.csv - CSV data file containing the data used to produce FIG. 5. This includes the Average superfluid velocity () as a function of height (z) for the 3 cases v=0.3c, v=0.6c, and v=0.9c. Instruments / Hardware / Software used: Bespoke FORTRAN numerical simulation software written to solve the Gross–Pitaevskii equation in three dimensions.
