Pattern Formation in Self-Propelled Particles with Density-Dependent Motility
Pattern Formation in Self-Propelled Particles with Density-Dependent Motility
We study the behavior of interacting self-propelled particles, whose self-propulsion speed decreases with their local density. By combining direct simulations of the microscopic model with an analysis of the hydrodynamic equations obtained by explicitly coarse graining the model, we show that interactions lead generically to the formation of a host …
