example of a vibrating particle self-propelling through a resonant interaction with its own …

Walking droplets through the lens of dynamical systems

A Rahman, D Blackmore - Modern Physics Letters B, 2020 - World Scientific
Over the past decade the study of fluidic droplets bouncing and skipping (or “walking”) on a
vibrating fluid bath has gone from an interesting experiment to a vibrant research field. The …

A hydrodynamic analog of Friedel oscillations

PJ Sáenz, T Cristea-Platon, JWM Bush - Science advances, 2020 - science.org
We present a macroscopic analog of an open quantum system, achieved with a classical
pilot-wave system. Friedel oscillations are the angstrom-scale statistical signature of an …

Lorenz-like systems emerging from an integro-differential trajectory equation of a one-dimensional wave–particle entity

RN Valani - Chaos: An Interdisciplinary Journal of Nonlinear …, 2022 - pubs.aip.org
Vertically vibrating a liquid bath can give rise to a self-propelled wave–particle entity on its
free surface. The horizontal walking dynamics of this wave–particle entity can be described …

Unsteady dynamics of a classical particle-wave entity

RN Valani, AC Slim, DM Paganin, TP Simula, T Vo - Physical Review E, 2021 - APS
A droplet bouncing on the surface of a vertically vibrating liquid bath can walk horizontally,
guided by the waves it generates on each impact. This results in a self-propelled classical …

[HTML][HTML] Dynamics, interference effects, and multistability in a Lorenz-like system of a classical wave–particle entity in a periodic potential

J Perks, RN Valani - Chaos: An Interdisciplinary Journal of Nonlinear …, 2023 - pubs.aip.org
A classical wave–particle entity (WPE) can be realized experimentally as a droplet walking
on the free surface of a vertically vibrating liquid bath, with the droplet's horizontal walking …

Collective vibrations of confined levitating droplets

SJ Thomson, MMP Couchman, JWM Bush - Physical Review Fluids, 2020 - APS
We report the results of our investigation of a fluid-based driven-dissipative oscillator system
consisting of a lattice of millimetric fluid droplets bouncing on a vertically vibrating liquid bath …

Pilot-wave dynamics in a rotating frame: the onset of orbital instability

N Liu, M Durey, JWM Bush - Journal of Fluid Mechanics, 2023 - cambridge.org
We report the results of a theoretical investigation of the stability of a hydrodynamic
analogue of Landau levels, specifically circular orbits arising when a millimetric droplet self …

A macroscopic, self-propelled wave-particle entity (WPE) that emerges as a walking droplet
on the surface of a vibrating liquid bath exhibits several hydrodynamic quantum analogs. We …
