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…
Motion of Euglena Gracilis: Active Fluctuations and Velocity Distribution
Pawel Romanczuk, Maksym Romensky, Dimitri Scholz +2
We study the velocity distribution of unicellular swimming algae Euglena gracilis using optical microscopy and theory. To characterize a peculiar feature of the experimentally obse…
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…
Active Brownian agents with concentration-dependent chemotactic sensitivity
Marcel Meyer, Lutz Schimansky-Geier, Pawel Romanczuk
We study a biologically motivated model of overdamped, autochemotactic Brownian agents with concentration-dependent chemotactic sensitivity. The agents in our model move stochastic…
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…
Swarming and Pattern Formation due to Selective Attraction and Repulsion
Pawel Romanczuk, Lutz Schimansky-Geier
We discuss the collective dynamics of self-propelled particles with selective attraction and repulsion interactions. Each particle, or individual, may respond differently to its ne…
