Fig. 2: Vison O(3) order parameter ∣ϕ∣ as a function of V.

The two dashed lines are guides to the eye for the position of the LN–VP first-order transition and the VP–QSL continuous transition. The error bars here represent the standard error of the mean, which is calculated as \(\sigma /\sqrt{N}\), where σ is one standard deviation and N is the total number of independent samples.
