FIG. 1.

Crystallizability of monodisperse hard aspherical particles characterized in terms of two shape parameters A and q. Filled circles indicate particles that easily crystallized, while open squares indicate particles that did not. The solid line is constructed by hand selecting a number of key points along the boundary between the two regimes, and by finding the simplest polynomial function fitting the data; the dashed line represents a prediction of the crystallizability limit from the current work; see below. Figure adapted from Ref. 25.

Coexistence pressure vs Aq for shape-polydisperse systems of hard aspherical particles. The solid line is a fit to the data for . Inset: Distribution of q values for polydisperse systems with = 4, 6, 8, and 12. Recall that q is independent of . The distribution is significantly larger and broader for than for the larger values of . The standard deviations of these distributions are: 0.055 for , 0.087 for , 0.123 for , and 0.190 for .

Coexistence pressure vs. Aq for monodisperse systems of hard aspherical particles with , . The line is a fit obtained from the data presented in Fig. 2 for polydisperse systems with , 8, and 12. The cross indicates the position of the polydisperse system with , . Points at the extremes of the q distribution are shaded with a lighter color (green).
