The criticality of the jamming transition responsible for amorphous solidification has been theoretically linked to the marginal stability of a thermodynamic Gardner phase. While the critical exponents of jamming appear independent of the preparation history, the pertinence of Gardner physics far from equilibrium is an open question. To fill this gap, we numerically study the nonequilibrium dynamics of hard disks compressed towards the jamming transition using a broad variety of protocols. We show that dynamic signatures of Gardner physics can be disentangled from the aging relaxation dynamics. We thus define a generic dynamic Gardner crossover regardless of the history. Our results show that the jamming transition is always accessed by exploring increasingly complex landscape, resulting in the anomalous microscopic relaxation dynamics that remains to be understood theoretically.

简单结构玻璃中的动态加德纳分频器

导致非晶凝固的干扰转变的临界性在理论上与热力学加德纳相的边际稳定性有关。虽然干扰的关键指数似乎与制备历史无关，但加德纳物理学远离平衡的相关性是一个悬而未决的问题。为了填补这一空白，我们使用各种协议对压缩到干扰转换的硬盘的非平衡动力学进行了数值研究。我们表明，加德纳物理学的动态特征可以与老化松弛动力学分开。因此，无论历史如何，我们都定义了一个通用的动态 Gardner 交叉。我们的结果表明，干扰转换总是通过探索日益复杂的环境来实现的，
