Physics Colloquium: John Bush, "Pilot-wave hydrodynamics"Professor John Bush
Professor of Applied Mathematics in the Department of Mathematics at Massachusetts Institute of Technology
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.
These walking droplets propel themselves by way of a resonant interaction with their own wave field, and so represent a macroscopic realization of the pilot-wave dynamics envisaged by Louis de Broglie. New theoretical developments provide rationale for the complex behavior of the bouncing droplets, and yield a trajectory equation for the walking droplets. Experimental and theoretical results in turn reveal and rationalize the emergence of quantization and wave-like statistics from pilot-wave dynamics in a number of settings.
