Bouncing Drops - is there a relationship to Quantum Mechanics?
Mogens T. Levinsen, NBI

Some years ago Y. Couder and E. Fort published some investigations on liquid drops "walking" on a liquid surface. The drops surf on the wave they themselves have created, giving a kind of system with a particle on a guiding wave analogous to de Broglie's pilot wave theory of Quantum Mechanics. Several quantum-like behaviors of the drops as for instance tunneling have been observed and in 2006 Couder and Fort published a thought provoking paper claiming the existence of Q.M. like interference patterns in the for Quantum Mechanics crucial double-slit experiment. I will discuss our own attempts to reproduce the results claimed, which have completely failed, and give a critique of various shortcomings and the statistics involved in Couder and Fort's experiment.
