WebSep 6, 2015 · In the Faraday pilot-wave fluid droplet dynamics, the fluid wave is meant as an analogy for the wavefunction. More specifically, the experiments are constructed as physical implementations analogous to the de Broglie-Bohm theory, where a particle with discrete coordinates is 'guided' by a pilot wave which follows the Schrödinger equation.. …
WebA droplet may 'walk' across the surface of a vertically vibrating bath of the same fluid, due to the propulsive interaction with its wave field. This hydrodynamic pilot-wave system exhibits many dynamics previously believed to exist only in the quantum realm. Starting from first principles, we derive a discrete-time fluid model, whereby the ... Webdroplet guided by a precisely tuned Faraday wave [5]. When con ned to a circular container, an oil droplet can be made to bounce on a water surface supporting a Faraday wave within a small range of driving frequency and amplitude [6]. Within an even narrower parameter range, the Faraday wave can guide the oil droplet in a random walk across …
WebNov 29, 2024 · The Faraday wave-droplet system is a macroscopic hydrodynamic analogue of what de Broglie envisioned in quantum mechanics as a pilot-wave system [5,6]. Harris and Bush [ 7 ] have a YouTube video displaying the droplet dynamics in a way which is quite useful for the modeling to be presented.
