    • In what follows, we use ripplon energies calculated for a spherical incompressible droplet, (Formula presented) (Ref. 24). A model-independent dispersion relation (Ref. 25) predicts an energy for the L = 2 ripplon that is at least 40% larger than the value we have used

    • By differentiation of the sum of bulk and surface energies with respect to He particle number, one finds that (Formula presented). This is similar to numerical diffusion Monte Carlo results (Ref. 25)

    • In the hollow-core model, the vorticity κ can be taken as homogeneously distributed over the entire core volume or concentrated in a singular filament at the center. As described in Ref. 19, the difference lies only in a reinterpretation of the core radius
