Mobility-Network Topology Carries Incremental Information About Future Aging Dynamics in a Glass-Forming Liquid

The study uses leakage-free simulations of an aging Kob-Andersen liquid with 2,028 particles and 200 trajectories at three temperatures. Mobility-network topology improves out-of-fold R² by ΔR² = 0.0049–0.0122, with the gain increasing monotonically with quench depth and retaining at least 98% atop softness-class baselines.
