Query: Crystallization and arrest mechanisms of model colloids   We performed dynamic simulations of spheres with short-range attractive
interactions for many values of interaction strength and range. Fast
crystallization occurs in a localized region of this parameter space, but the
character of crystallization pathways is not uniform within this region.
Pathways range from one-step, in which a crystal nucleates directly from a gas,
to two-step, in which substantial liquid-like clusters form and only
subsequently become crystalline. Crystallization can fail because of slow
nucleation from either gas or liquid, or because of dynamic arrest caused by
strong interactions. Arrested states are characterized by the formation of
networks of face-sharing tetrahedra that can be detected by a local common
neighbor analysis.
