摘要

我们讨论了单分散硬球的过饱和悬浮液中的晶体形成，其中硬球的浓度在空间和时间上随机固定。钉接过程引入了外部长度尺度和外部时间尺度，它们限制了可访问的构型数量，并最终限制了导致结晶的途径数量。我们观察到，在特定的钉钉浓度下，成核率密度显著下降，这可能与临界核的结构及其在未钉钉体系中形成的动力学直接相关。

Influence of Random Pinning on the Crystallization Process in Suspensions of Hard Spheres

We discuss crystal formation in supersaturated suspensions of monodisperse hard spheres with a concentration of hard spheres randomly pinned in space and time. The pinning procedure introduces an external length scale and an external time scale that restrict the accessible number of configureurations and ultimately the number of pathways leading to crystallization. We observe a significant drop in the nucleation rate density at a characteristic pinning concentration that can be directly related to the structure of the critical nucleus and the dynamics of its formation in the unpinned system.
