Memory Formation in Jammed Hard Spheres.
Abstract
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.
