Extended Data Fig. 5: Changing n or V.
a, Plotting \({n}_{0}^{2/3}\) versus tuni = t − t* for all 11 datasets taken with the same n and V (see Extended Data Fig. 2), together with the two further sets taken with reduced n (purple triangles) or V (green pentagons), shows that the rate of growth of \({n}_{0}^{2/3}\) depends on the gas density and the system size. b, However, the rate of growth of ℓ2 in the scaling regime is universal. The only effect of the system size is that, for lower V, the saturation of ℓ2 occurs at a lower value (dashed line shows V2/3 for the smaller box).
