Depinning dynamics of repulsively interacting particle systems with different force ranges

We apply Langevin simulation to the depinning dynamics of different two-dimensional model systems on the disordered substrate. Each model system is composed of Janus particles interacting with each other through two purely repulsive interactions with varying ranges of forces. We find two thresholds of the driving force exist in each model system. The interference of two interparticle repulsive interactions with similar short force ranges is more conducive to forming dynamic ordering structures above the depinning. The results help reveal the mechanism of ordering in the multiscale interacting particle systems.
