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…

Geometrically-protected reversibility in hydrodynamic Loschmidt-echo experiments
Raphaël Jeanneret, Denis Bartolo
We demonstrate an archetypal Loschmidt-echo experiment involving thousands of droplets which interact in a reversible fashion via a viscous fluid. Firstly, we show that, unlike equ…
