Superfluid Helium — Vortex Lattice

Ω (rotation) 0.50 Temperature 0.30 κ (vortex core) 0.08 Perturb Reset

In rotating superfluid He-II, angular momentum is carried by quantized vortex filaments (circulation = nκ, κ=h/m). They arrange into a triangular Abrikosov-like lattice. Areal density: n_v = 2Ω/κ. Vortex core size ~ healing length ξ.
