The Countoscope for self-propelled particles
Tristan Cerdin, Talia Calazans, Carine Douarche +1
Particle number fluctuations , measured in virtual observation boxes of an image or a simulation, offer a way to quantify particle dynamics when particle tracking is impracti…
Number fluctuations distinguish different self-propelling dynamics
Tristan Cerdin, Sophie Marbach, Carine Douarche
In nonequilibrium suspensions, static number fluctuations in virtual observation boxes reveal remarkable structural properties, but the dynamic potential of signals rema…
Local chemotactic response of in fluid and near surfaces
Adam Gargasson, Julien Bouvard, Carine Douarche +2
Bacteria can adjust their swimming behaviour in response to chemical variations, a phenomenon known as chemotaxis. This process is characterised by a drift velocity that depends no…
Bacteria collective motion is scale-free
Benjamin Perez-Estay, Vincent Martinez, Carine Douarche +7
Suspensions of swimming bacteria interact hydrodynamically over long ranges, organizing themselves into collective states that drive large-scale chaotic flows, often referred to as…
Active Saffman-Taylor Viscous Fingering
Akash Ganesh, Carine Douarche, Harold Auradou
Adding swimming bacteria to a liquid causes its effective shear viscosity to decrease, eventually reaching a regime of zero viscosity. We examined whether this property leads to vi…
Direct measurement of the aerotactic response in a bacterial suspension
J. Bouvard, C. Douarche, P. Mergaert +2
Aerotaxis is the ability of motile cells to navigate toward oxygen. A key question is the dependence of the aerotactic velocity with the local oxygen concentration c. Here we combi…
