The pilot-wave dynamics of walking droplets

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
