论文摘要
在过去的二十年中，大量研究涉及硬球悬浮液中晶体成核的话题。所有这些努力的共同结果是，在低超饱和度下，实验观察到的成核速率和数值计算的速率差异超过十个数量级。我们提出了元稳定硬球液体中晶核速率密度的精确模拟结果。为了将这些速率密度与实验测量值进行比较，我们提出了将实验数据解释为成核和晶体生长过程的组合（而不是纯粹的成核过程）。这种解释可能会解决有关不同率的长期争议。
Over the past two decades, a large number of studies addressed the topic of crystal nucleation in suspensions of hard spheres. The shared result of all these efforts is that, at low super-saturations, experimentally observed nucleation rates and numerically computed ones differ by more than ten orders of magnitude. We present precise simulation results of crystal nucleation rate densities in the meta-stable hard sphere liquid. To compare these rate densities to experimentally measured ones, we propose an interpretation of the experimental data as a combination of nucleation and crystal growth processes (rather than purely the nucleation process). This interpretation may resolve the long standing dispute about the differing rates.
