Quantized circulation and vortex array

Purpose

Rotate a 2D condensate at angular frequency $\Omega$ and count the equilibrium vortex number $N(\Omega)$ .

What it proves

The simulation sits exactly on the Feynman quantisation line $N = 2\Omega R^{2} m / \hbar$ — the canonical superfluid signature.

Relation to current theory

Validated against the Osheroff and Packard He-II experiments to ppm precision. A direct sanity check that the solver reproduces known condensate physics before we trust its cosmological output.
