Superradiance and subradiance occur in quantum optics when the emission rate of photons from multiple atoms is enhanced and diminished, respectively, owing to interaction between neighboring atoms. We here demonstrate a classical analog thereof in a theoretical model of droplets walking on a vibrating bath. Two droplets are confined to identical two-level systems, a pair of wells between which the drops may tunnel, joined by an intervening coupling cavity. The resulting classical superradiance…

The Super of Superradiance
TLDR
Cooperative single-photon emission from an atom ensemble will provide insights into quantum electrodynamics and applications in quantum communication and describe the cooperative, spontaneous emission of photons from a collection of atoms.

TLDR
A laboratory realization of the gedanken experiment that Dicke used to introduce superradiance is reported, where two Ba/sup +/ ions are laser-cooled and crystallized in a microscopic Paul trap so that they come to rest 1.5 microns from each other.
Unpredictable tunneling of a classical wave-particle association.
TLDR
This work investigates the motion of a walker when it collides with barriers of various thicknesses and shows that this wave-particle association has a nonlocality sufficient to generate a quantumlike tunneling at a macroscopic scale.
Single-particle diffraction and interference at a macroscopic scale.
TLDR
A droplet bouncing on a vertically vibrated bath can become coupled to the surface wave it generates and become a "walker" moving at constant velocity on the interface, and diffraction or interference patterns are recovered in the histogram of the deviations of many successive walkers.
Tunneling with a hydrodynamic pilot-wave model

TLDR
It is shown that, for a uniform background velocity and within the small wavelength approximation, the stopping of gravity waves is described by a stationary saddle-node bifurcation due to the spatial resonance of an incident wave with the converted "blueshifted" wave.

TLDR
It is demonstrated that the interaction with the recently emitted waves can be modeled by a Rayleigh-type friction, and a basic framework for further investigations of wave-particle interactions when memory effects are included.

TLDR
The walking droplet system discovered by Yves Couder and Emmanuel Fort presents an example of a vibrating particle self-propelling through a resonant interaction with its own wave field, and a generalized theoretical framework that provides a mathematical bridge between the hydrodynamic pilot-wave system and various realist models of quantum dynamics is described.
