Dynamic heterogeneity flow promotes binding reactions in a dense system of hard annular sector particles.

We perform molecular dynamics simulations on a system of hard annular sector particles (ASPs) to investigate the reaction-dynamics relationship. The dimerization reaction zone, mixing reaction zone including dimerization and n-merization (n > 2), and arrested region are observed successively as area fraction φ increases from low to high. In this work, we focus on the properties of the concentrated arrested region (φ≥ 0.
