Phase-Locking Parametric Instability Coupling Longitudinal and Transverse Waves on Rivulets in a Hele-Shaw Cell
Grégoire Le Lay, Adrian Daerr
We report an instability exhibited by a fluid system when coupling two distinct types of waves, both linearly damped. While none of them is unstable on its own, they amplify one an…
Magnetic levitation in the field of a rotating dipole
Grégoire Le Lay, Sarah Layani, Adrian Daerr +5
It is well known that two permanent magnets of fixed orientation will either always repel or attract one another regardless of the distance between them. However, if one magnet is…
Active Young-Dupré Equation: How Self-organized Currents Stabilize Partial Wetting
Yongfeng Zhao, Ruben Zakine, Adrian Daerr +3
The Young-Dupré equation is a cornerstone of the equilibrium theory of capillary and wetting phenomena. In the biological world, interfacial phenomena are ubiquitous, from the spre…
The ping pong ball water cannon
Bruno Andreotti, Wladimir Toutain, Camille Noûs +3
The course "Phy Ex" was created by Yves Couder in the Paris VII university to teach experimental physics through projects. In this article, we present this teaching method through…
The charmed string: self-supporting loops through air drag
Adrian Daerr, Juliette Courson, Margaux Abello +2
The string shooter experiment uses counter-rotating pulleys to propel a closed string forward. Its steady state exhibits a transition from a gravity dominated regime at low velocit…
Surface Tensions between Active Fluids and Solid Interfaces: bare vs dressed
Ruben Zakine, Yongfeng Zhao, Miloš Knežević +4
We analyze the surface tension exerted at the interface between an active fluid and a solid boundary in terms of tangential forces. Focusing on active systems known to possess an e…
