Fig. 3: Nonlocal scenario for structure relaxation at a particle level.

a Self-intermediate scattering function \({F}_{s}(k,t)\) of each particle (background data) and the whole system (dark blue circles) for a 2D PM (\(\Delta\,=\,13 \%\)) at \(T\,=\,0.0018\). b Correlation between microscopic relaxation time (\({\tau }_{\alpha }\) for each particle, see text for its definition) and structural order as functions of coarse graining length \(L\). As indicated by the arrow, different curves correspond to decreasing temperatures, \(T\,=\,0.0037\), \(0.0028\), \(0.0023\), and \(0.0018\). The peak positions are indicated by black circles. c–e For the same state point as panel a, typical snapshots of inverse of microscopic relaxation time \(1/{\tau }_{\alpha }\) (panel c), bare structural order \(\Theta\) (panel d), and structural order \({\Theta }_{{\rm{CG}}}\) coarse grained at \(L\,=\,3.8\) (panel e), where \({C}_{r}\) shows a peak in panel b.
