Controlling microalgae populations by phototactic memory
Gianni Jacucci, Davide Breoni, Pierre Illien +4
Understanding how microorganisms navigate in complex environments is a central question in active matter and biological physics. Phototaxis - the ability to use light as a navigati…
Hydrodynamic Instabilities of Active Jets
Marco Vona, Isabelle Eisenmann, Nicolas Desprat +3
Using a combination of theory, experiments, and numerical simulations, we investigate the stability of coherent structures in a suspension of strongly aligned active swimmers. We s…
Pure hydrodynamic instabilities in active jets of "puller" microalgae
Isabelle Eisenmann, Marco Vona, Nicolas Desprat +3
Active fluids can develop spontaneous flow instabilities and complex patterns. However, spatio-temporal control of active particles has remained challenging, despite its relevance…
Phototactic Decision-Making by Micro-Algae
Shantanu Raikwar, Adham Al-Kassem, Nir S. Gov +3
We study how simple eukaryotic organisms make decisions in response to competing stimuli in the context of phototaxis by the unicellular alga . While neg…
