Extended Data Fig. 9: Diffusive motion and the comparison with diffusionless ordering model.
a, The time evolution of the mean-square displacement Δr(t)2 for final crystals, initial crystals, and unlayered liquid in experiments (κσ ~ 3.2, T ~ 0.4Tm). We illustrate τave and τα by vertical green and orange lines, respectively. b, The time evolution of the mean-square displacement Δr(t)2 for bulk samples at various T in simulations (κσ ~ 2.0). we illustrate τave by vertical green line. The subdiffusive behavior becomes obvious at deep supercoolings. c, The diffusive constant determined in b and the comparison between diffusive and diffusionless models. Diffusive constant D (top) is determined as \({{\Delta }}\,r{({\tau }_{{\rm{ave}}})}^{2}/6{\tau }_{{\rm{ave}}}\).
