我们详细讨论了所谓的“老化”现象，这种现象出现在各种“玻璃状”系统中，包括自旋玻璃、聚合物或玻璃状液体。介绍并比较了解释这种老化现象的简单模型（特别是通过平均场模型获得的见解及其可能的局限性）。我们讨论“陷阱模型”，它描述了真实或相空间中的间歇动力学，其中老化现象以一种特别有趣的方式出现。最后，我们引入了“自我诱导”猝灭紊乱的概念，它允许在类似的基础上治疗无序和非无序（但复杂）的系统。
We discuss in details the so-called ‘aging’ phenomenon, which appears in a large variety of ‘glassy’ systems, including spin-glasses, polymers, or glassy liquids. Simple models accounting for this aging phenomenon are introduced and compared (in particular insights obtained via mean field models, and their possible limitations). We discuss the ‘trap model’ which describes intermittent dynamics in real or phase-space, where the aging phenomenon appears in a particularly interesting way. Finally, we introduce the idea of ‘self-induced’ quenched disorder, which allows to treat disordered and non disordered (but complex) systems on a similar footing.
