Study of cluster crystals with two different stochastic models and two different repulsive potentials

Abstract

[eng] We study numerically two-dimensional active cluster crystals using two different repulsive soft-core potentials. We analyze two different models of the active dynamics: active Brownian particles and Ornstein-Uhlenbeck particles. We show a tendency of particles to aggregate depending on the parameters. To compare them, we use the radial distribution function which helps to analyze the distribution of the particles inside a single cluster.
