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
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.

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.
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.
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
Eddi et al. [Phys. Rev Lett. 102, 240401 (2009)] presented experimental results demonstrating the unpredictable tunneling of a classical wave-particle association as may arise when a droplet walking
Pilot-Wave Hydrodynamics
Yves Couder, Emmanuel Fort, and coworkers recently discovered that a millimetric droplet sustained on the surface of a vibrating fluid bath may self-propel through a resonant interaction with its own
Wave-current interaction as a spatial dynamical system: analogies with rainbow and black hole physics.
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.
Metastable entangled states of atomic systems in macroscale: radiation dynamics and spectrum
Dynamics of spontaneous decay and corresponding emission spectrum are exactly treated for a system of two identical two-level atoms in 1D. Just a one-dimensional case is considered in order to

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.

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.
