The pilot wave dynamics of walking droplets

Fluiddynamik-Experiment gibt neue Einblicke in den Welle-Teilchen-Dualismus By Daniel M. Harris & John W. M. Bush Department of Mathematics, MIT Further information: ~bush/?page_id=484 Background: It has been known for some time that a drop can bounce indefinitely on the surface of a vibrating fluid bath [1]. Recently it has come to light that millimetric droplets can propel themselves across the surface of a vibrating fluid bath by virtue of their pilot-wave dynamics, and that these walking droplets exhibit several features previously thought to be exclusive to the microscopic quantum realm, including single-particle diffraction, tunneling, quantized orbits and orbital level splitting [2, 3, 4, 5, 6, 7, 8]. In the video, we explore the pilot-wave dynamics of walking droplets. We first review the basic principles of the walking droplet system and then present the results of an experimental investigation of a walking droplet confined to cir
