Correlation length during the ramp, shown with and without rescaling (main and inset, respectively) and two-sided logarithmic axes for ∣ τ ∣ > τ KZ . ξ KZ is found from fitting ξ ( τ = τ KZ ) = ξ 0 ( τ KZ / t r ) − β with β = 0.9(1) (difference from β = ν = 0.67 expected to be due to finite-size effects). Dashed coloured lines show the theoretically expected scaling, f ( x ) = ∣ x ∣ − ν with ν = 0.67 for x < −1 (purple) and a heuristic f ( x ) = x η with η = 1 for x > 1 (teal). The increase in ξ beyond the freezing point (diamond) causes deviation from KZ predictions.
