Nutrient transport driven by microbial active carpets
Arnold J. T. M. Mathijssen, Francisca Guzmán-Lastra, Andreas Kaiser +1
We demonstrate that active carpets of bacteria or self-propelled colloids generate coherent flows towards the substrate, and propose that these currents provide efficient pathways…
Focusing of Active Particles in a Converging Flow
Mykhailo Potomkin, Andreas Kaiser, Leonid Berlyand +1
We consider active particles swimming in a convergent fluid flow in a trapezoid nozzle with no-slip walls. We use mathematical modeling to analyze trajectories of these particles i…
Active dipole clusters: from helical motion to fission
Andreas Kaiser, Katarina Popowa, Hartmut Löwen
The structure of a finite particle cluster is typically determined by total energy minimization. Here we consider the case where a cluster of soft sphere dipoles becomes active, i.…
