Fig. 4. — Partial memory effect in ordinary glasses. Distributions of cage-relative distances between clones P(Δ_ab) for ordinary glasses first compressed for t_w = 2¹⁸ × 100 at pressure Z and then decompressed back to Z_s = 200 for a short time t = 2⁸ × 100. The results are compared to the reference curve (cyan line) which only aged for a short time t = 2⁸ × 100 at Z_s = 200. Deviations with the reference distribution at large Δ_ab are due to aging relaxation dynamics which is irreversible.
