- Abstract: Superradiance occurs when a collection of atoms exhibits cooperative,
spontaneous emission of photons at a rate that exceeds that of its component
parts. Here, we reveal a similar phenomenon in a hydrodynamic system consisting
of a pair of vibrationally-excited cavities, coupled through their common
wavefield, that spontaneously emit droplets via interfacial fracture. We show
that the droplet emission rate of two coupled cavities is higher than the
emission rate of two isolated cavities. We further show that the amplified
emission rate varies sinusoidally with distance between the cavities, thus
demonstrating a hydrodynamic phenomenon that captures the essential features of
superradiance in optical systems.

Recent advances in manipulating droplet emissions from a thin vibrating fluid using submerged cavities have introduced an innovative platform for generating hydrodynamic analogs of quantum and optical systems.

emitters via two-photon excitation [49.1574468325115]
Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

Dicke superradiance describes the collective radiative decay of a fully inverted ensemble of two-level atoms.
We experimentally investigate this effect for a chiral, i.e.,direction-dependent light--matter coupling.
Our results shed light on the collective radiative dynamics of cascaded quantum many-body systems.

waveguide QED [0.0]
We investigate whether an array of emitters coupled to a one-dimensional bath undergoes Dicke superradiance.
Many-body superradiance occurs because the initial fluctuation that triggers the emission is amplified throughout the decay process.
Superradiant bursts may thus be a smoking gun for the generation of correlated photon states of exotic quantum statistics.

We consider the cooperative spontaneous emission of a system of two identical atoms, interacting with the electromagnetic field in the vacuum state.
Using time-dependent theory, we investigate the spectrum of the radiation emitted by the two-atom system.
We show that it is modulated in time, and that the presence of the oscillating mirror can enhance or inhibit the decay rate.

In spite of particle losses the quantum entanglement propagation exhibits a ballistic character with propagation speeds related to the differerent quasiparticles that are involved in the dynamics.
Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
