Abstract A new class of self-propelled droplets, coined superwalkers, has been shown to emerge when a bath of silicone oil is vibrated simultaneously at a given frequency and its subharmonic tone with a relative phase difference between them (Valani et al., Phys. Rev. Lett., vol. 123, 2019, 024503). To understand the emergence of superwalking droplets, we explore their vertical and horizontal dynamics by extending previously established theoretical models for walkers driven by a single… 

Stop-and-go locomotion of superwalking droplets.

The emergence of stop-and-go motion of droplets is predicted, consistent with experimental observations, and lays a foundation for further studies of dynamically driven droplets, whereby the droplet's motion may be guided by engineering arbitrary time-dependent phase difference functions.

Unsteady dynamics of a classical particle-wave entity.

The dynamical and statistical aspects of irregular walking are explored and an equivalence between the droplet dynamics and the Lorenz system is shown, as well as making connections with the Langevin equation and deterministic diffusion.

Pseudo-laminar chaos from on-off intermittency

In finite-dimensional, chaotic, Lorenz-like wave-particle dynamical systems one can find diffusive trajectories, which share their appearance with that of laminar chaotic diffusion [Phys. Rev. Lett. 128,

Anomalous transport of a classical wave-particle entity in a tilted potential.

A classical wave-particle entity in the form of a millimetric walking droplet can emerge on the free surface of a vertically vibrating liquid bath. Such wave-particle entities have been shown to

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

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 adequately

Oscillons, walking droplets, and skipping stones (an overview)

This article considers additional phenomena that complement the earlier topics addressed by Ibrahim [(Liquid Sloshing Dynamics: Theory and Applications. Cambridge University Press, Cambridge, 2005),

Faraday waves under perpendicular electric field and their application to the walking droplet phenomenon

Vertically oscillating fluid surfaces have been a subject extensively studied in the past, as well as surface instabilities produced by electrohydrodynamic waves in similar configurations. In the



Walking droplets in a circular corral: Quantisation and chaos.

This work examines experimentally the dynamics of a walker inside a circular corral and illustrates the emergence of a variety of stable dynamical states for relatively low vibrational accelerations, which lead to a double quantisation in angular momentum and orbital radius.

Drops bouncing on a vibrating bath

Orbiting pairs of walking droplets: Dynamics and stability

A decade ago, Couder and Fort [Phys. Rev. Lett. 97, 154101 (2006)] discovered that a millimetric droplet sustained on the surface of a vibrating fluid bath may self-propel through a resonant

Superwalking Droplets.

A new class of walking droplets is observed, which is dubbed superwalkers, which may be more than double the size of the largest walkers, may travel at more than triple the speed of the fastest ones, and enable a plethora of novel multidroplet behaviors.

Walking droplets correlated at a distance.

It is demonstrated that two oscillating particles (millimetric droplets) confined to separate potential wells exhibit correlated dynamical features, even when separated by a large distance, which is reminiscent of entanglement.

Quasi-normal free-surface impacts, capillary rebounds and application to Faraday walkers

We present a model for capillary-scale objects that bounce on a fluid bath as they also translate horizontally. The rebounding objects are hydrophobic spheres that impact the interface of a bath of
