Mobility-network topology carries incremental, softness-orthogonal information about future aging dynamics in a glass-forming liquid
Abstract
Does the spatial organization of particle mobility in a glass predict future motion beyond what local structure knows? In leakage-free simulations of an aging Kob--Andersen liquid (N=2028; 200 trajectories; three temperatures), mobility-network topology raises the out-of-fold R2 by dRtwo=0.0049--$0.0122$, monotonically with quench depth, retaining ≥ 98% atop softness-class baselines. Giant mobile components are dense hotspots whose members subsequently quiet down: exhaustion zones of cooperative motion --- a spatial anticorrelation channel invisible to single-particle descriptors.
