Irreversibility and self-organisation in hydrodynamic echo experiments
Gustavo During, Denis Bartolo, Jorge Kurchan
We discuss the reversible-irreversible transition in low-Reynolds hydrodynamic systems driven by external cycling actuation. We introduce a set of models with no auto-organisation,…
No many-scallop theorem: Collective locomotion of reciprocal swimmers
Eric Lauga, Denis Bartolo
To achieve propulsion at low Reynolds number, a swimmer must deform in a way that is not invariant under time-reversal symmetry; this result is known as the scallop theorem. We sho…
Rotational dynamics of a soft filament: wrapping transition and propulsive forces
Naïs Coq, Olivia Du Roure, Joel Marthelot +2
We analyze experimentally the shape of a long elastic filament rotating in a viscous liquid. We identify a continuous but sharp transition from a straight to an helical shape, resu…
Bouncing or sticky droplets: impalement transitions on superhydrophobic micropatterned surfaces
Denis Bartolo, Farid Bouamrirene, Emilie Verneuil +3
When a liquid drops impinges a hydrophobic rough surface it can either bounce off the surface (fakir droplets) or be impaled and strongly stuck on it (Wenzel droplets). The analysi…
Retraction dynamics of aquous drops upon impact on nonwetting surfaces
Denis Bartolo, Christophe Josserand, Daniel Bonn
We study the impact and subsequent retraction dynamics of liquid droplets upon high-speed impact on hydrophobic surfaces. Performing extensive experiments, we show that the drop re…
Effects of intermediate bound states in dynamic force spectroscopy
Imre Derenyi, Denis Bartolo, Armand Ajdari
We revisit here some aspects of the interpretation of dynamic force spectroscopy experiments. The standard theory predicts a typical unbinding force linearly proportional to…
