Walking droplets in a Faraday-Talbot corral

Abstract

In this experiment we study the motion of a walking droplet on the surface of a vibrated fluid, where the drop is confined within a circular corral defined by an array of pillars that protrude through the surface of the fluid. We demonstrate that in a certain acceleration range, just below the Faraday threshold, the long-time statistics of the droplet motion correlates with the eigenmode of the corral, referred to as the Faraday-Talbot pattern.
