Minimal Model for Dynamic Bonding in Colloidal Transient Networks
  We investigate a model for colloidal network formation using Brownian Dynamics computer simulations. Hysteretic springs establish transient bonds between particles with repulsive core. If a bonded pair is separated by a cutoff distance, the spring vanishes and reappears only if the two particles contact each other. We present results for the the bond lifetime distribution and investigate the properties of the van Hove dynamical two-body correlation function. The model displays crossover from fluid-like dynamics, via transient network formation, to arrested quasi-static network behavior.
