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…

Light-induced phase separation with finite wavelength selection in photophobic micro-algae
Isabelle Eisenmann, Alfredo L'Homme, Aliénor Lahlou +5
As for many motile micro-algae, the freshwater species Chlamydomonas reinhardtii can detect light sources and adapt its motile behavior in response. Here, we show that suspensions…
