“Quantum behavior at a macroscopic scale: Droplets walking on the impossible pilot wave”

 

ABSTRACT

 

Yves Couder and coworkers have recently discovered that droplets walking on a vibrating fluid bath exhibit several features previously thought to be peculiar to the microscopic, quantum realm, including single-particle diffraction and interference, tunneling, quantized orbits and orbital level splitting. Theoretical developments provide rationale for the complex behavior of the bouncing droplets, and yield a trajectory equation for the walking droplets. A correspondence is developed between this fluid system and de Broglie’s relativistic pilot-wave theory of quantum mechanics. New experiments are presented, and indicate the potential value of this hydrodynamic system for both visualizing and understanding quantum mechanics.
