Liquids equilibrated below an onset condition share similar inherent states, while those above that onset have inherent states that markedly differ. Although this type of materials memory was first reported in simulations over 20 years ago, its physical origin remains controversial. Its absence from mean-field descriptions, in particular, has long cast doubt on its thermodynamic relevance. Motivated by a recent theoretical proposal, we reassess the onset phenomenology in simulations using a fast hard sphere jamming algorithm and find it to be both thermodynamically and dimensionally robust. Remarkably, we also uncover a second type of memory associated with a Gardner-like regime of the jamming algorithm.

阻塞硬球中的记忆形成

在开始条件以下平衡的液体具有相似的固有状态，而在开始条件以上平衡的液体具有明显不同的固有状态。尽管这种材料记忆是20多年前在模拟中首次报道的，但其物理起源仍存在争议。特别是缺少平均场描述，一直以来对其热力学相关性产生怀疑。受近期理论建议的启发，我们使用快速硬球干扰算法重新评估了仿真中的现象学现象，发现它在热力学和尺寸方面都具有鲁棒性。值得注意的是，我们还发现了第二种与干扰算法的类似Gardner体制的存储器。
