We explore crystallisation and polymorph selection in active Brownian particles with numerical simulation. In agreement with previous work (Wysocki et al. in Europhys Lett 105:48004, 2014), we find that crystallisation is suppressed by activity and occurs at higher densities with increasing Péclet number (Pe\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength…

Contrary to a widespread assumption in the colloid literature, the occurrence of spontaneous crystallization within a bulk amorphous state does not prove that this state was an ergodic fluid rather than a glass.

The results confirm the picture established for 2D systems in which an activity-induced phase separation occurs, with strong analogies to equilibrium gas-liquid spinodal decomposition, in spite of the purely non-equilibrium nature of the driving force behind the phase separation.

Using molecular-dynamics simulations, this work studies the crystallization of the simplest glass-forming system, a hard-sphere glass, and finds that crystallization is caused by a subset of particles cooperatively undergoing large rearrangements in an intermittent stochastic fashion (avalanches).

The role of the softness of the pair interactions, different solvent viscosities, and different sedimentation rates in simulations that include HIs are explored, which might reflect the irrelevance of these three features on the nucleation process.
