Pattern formation in active particle systems due to competing alignment interactions
Robert Großmann, Pawel Romanczuk, Markus Bär +1
Recently, we proposed a self-propelled particle model with competing alignment interactions: nearby particles tend to align their velocities whereas they anti-align their direction…
Vortex arrays and meso-scale turbulence of self-propelled particles
Robert Grossmann, Pawel Romanczuk, Markus Bär +1
Inspired by the Turing mechanism for pattern formation, we propose a simple self-propelled particle model with short-ranged alignment and anti-alignment at larger distances. It is…
Self-propelled particles with selective attraction-repulsion interaction - From microscopic dynamics to coarse-grained theories
Robert Grossmann, Lutz Schimansky-Geier, Pawel Romanczuk
In this work we derive and analyze coarse-grained descriptions of self-propelled particles with selective attraction-repulsion interaction, where individuals may respond differentl…
