Abstract

In a recent paper, Di Lisio et al. [J. Chem. Phys. 159, 064505 (2023)] analyzed a series of temperature down-jumps using the single-parameter aging (SPA) ansatz combined with a specific assumption about density scaling in the out-of-equilibrium system and did not find a good prediction for the largest down-jumps. In this paper, we show that SPA in its original form does work for all their data, including large jumps of ΔT > 20 K. Furthermore, we discuss different approaches to the extension of the density scaling concept to out-of-equilibrium systems.

单参数老化和密度缩放。

在最近的一篇论文中，Di Lisio 等人[J. Chem. Phys. 159, 064505 (2023)]使用单参数老化（SPA）解析结合失衡系统中密度缩放的特定假设分析了一系列温度下跃，但没有发现对最大下跃的良好预测。此外，我们还讨论了将密度缩放概念扩展到非平衡系统的不同方法。
