Fig. 1: Three different structural states of 2D vortices/rotors.
From: Hyperuniformity and phase enrichment in vortex and rotor assemblies
(A) Hyperuniformity for Euler point vortices, (B) Hyperuniformity for QG rotors/surface rotors, (C) Phase enrichment induced by circulation differences where green (black) represents vortices of high (low) circulation, and (D) Crystallization arising from hydrosteric interactions. The insets of (A), (B), and (C) show the structure factor, S(q). In (A) and (B), S(q) decays to zero at small q, indicating that the distribution is hyperuniform. In (C), the structure factor shows the six distinct peaks of a hexagonal lattice.
