Video Lesson – 07/06/2013 – Hydrodynamic Modelling of Pilot-Wave and boucing droplet coupling in a Faraday Problem

“Recent experiments by two groups, Yves Couder (Paris) and John 
Bush (MIT) have shown experimentally that droplets will bounce on the 
surface of a vertically vibrated bath (instead of coalescing with it), 
generating a Faraday-type wavefield at every bounce. From this state, a 
pitchfork symmetry breaking bifurcation leads to a “walking” state whereby 
the bouncing droplet is “guided” by the self-generated wavefield – the 
droplet’s pilot wave. Once this state is achieved a large array of 
interesting dynamics ensues with surprising analogies to quantum 
mechanical behaviour. We will present a coupled particle-fluid model that 
can can be used simulate the dynamics of this problem. This is joint work 
with John Bush, Andre Nachbin (IMPA) and Carlos Galeano (IMPA)”
