Extended Data Fig. 2: System size dependence of structural order parameters.
From: Ideal non-crystals as a distinct form of ordered states without symmetry breaking
The system size dependence of the average steric order parameter Θ (a) and the hexatic bond-orientational order parameter Ψ6 (b) for three temperatures at which the system can equilibrate via swap Monte Carlo simulations. The data points are presented as mean values ± s.d. of measurements taken from 1000, 200, and 100 samples for N = 1024, 4096, and 16384 systems, respectively. Both results indicate the absence of apparent finite-size effects. In particular, the value of Ψ6 is quite low at low temperatures and independent of the system size, suggesting that the hexagonal crystalline order is not favoured in our system.
