Deciphering the dual chemotaxis strategy of bacteria in porous media
Sönke Beier, Veronika Pfeifer, Agniva Datta +2
Chemotaxis of bacterial swimmers that move in a run-and-turn pattern is well studied in uniform bulk fluid. It is primarily based on modulating the run time in dependence on the sw…
Intermittent Run Motility of Bacteria in Gels Exhibits Power-Law Distributed Dwell Times
Agniva Datta, Sönke Beier, Veronika Pfeifer +2
While bacterial swimming has been well characterized in uniform liquid environments, only little is known about how bacteria propagate through complex environments, such as gel-lik…
The random walk of intermittently self-propelled particles
Agniva Datta, Carsten Beta, Robert Großmann
Motivated by various recent experimental findings, we propose a dynamical model of intermittently self-propelled particles: active particles that recurrently switch between two mod…
Non-Gaussian displacements in active transport on a carpet of motile cells
Robert Großmann, Lara S. Bort, Ted Moldenhawer +3
We study the dynamics of micron-sized particles on a layer of motile cells. This cell carpet acts as an active bath that propels passive tracer particles via direct mechanical cont…
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…
