Subradiance is the cooperative inhibition of the radiation by several emitters coupled to the same electromagnetic modes. It has been predicted by Dicke in 1954 and only recently observed in cold atomic vapors. Here we address the question to what extend this cooperative effect survives outside the limit of frozen two-level systems by studying the subradiant decay in an ensemble of cold atoms as a function of the temperature. Experimentally, we observe only a slight decrease of the subradiant…

Roles of cooperative effects and disorder in photon localization: the case of a vector radiation field

We numerically study photon escape rates from three-dimensional atomic gases and investigate the roles of cooperative effects and disorder in photon localization, while taking into account the



Subradiance in a Large Cloud of Cold Atoms.

This work reports the experimental observation of subradiance in an extended and dilute cold-atom sample containing a large number of particles, and detects a very slow decay, with time constants as long as 100 times the natural lifetime of the excited state of individual atoms.

Subradiance and radiation trapping in cold atoms

We experimentally and numerically study the temporal dynamics of light scattered by large clouds of cold atoms after the exciting laser is switched off, in the low intensity (linear-optics) regime.

Controlled Dicke subradiance from a large cloud of two-level systems.

It is shown that a dilute cloud of cold atoms is an ideal system to look for subradiant states in free space and study various mechanisms to control this subradiance.

Superradiance in a Large Cloud of Cold Atoms in the Linear-Optics Regime

Superradiance has been extensively studied in the 1970s and 1980s in the regime of superfluores-cence, where a large number of atoms are initially excited. Cooperative scattering in the linear-optics

Light transport in cold atoms and thermal decoherence.

The coherent backscattering interference effect is used to investigate experimentally and theoretically how coherent transport of light inside a cold atomic vapor is affected by the residual motion of atomic scatterers and derive analytical expressions for the corresponding coherence time.

Decay dynamics in the coupled-dipole model

Abstract Cooperative scattering in cold atoms has gained renewed interest, in particular in the context of single-photon superradiance, with the recent experimental observation of super- and

Observation of Dicke superradiance for two artificial atoms in a cavity with high decay rate.

Here, a close to ideal realization of Dicke's original two-spin Gedankenexperiment is presented, using a system of two individually controllable superconducting qubits weakly coupled to a fast decaying microwave cavity.

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.

Protected state enhanced quantum metrology with interacting two-level ensembles.

By redesign of the Ramsey-pulse sequence to include different rotations of individual spins that effectively fold the collective state onto a state close to the center of the Bloch sphere, partial protection from collective decoherence is possible and allows a significant improvement in the sensitivity limit of a clock transition detection scheme.

Exponential Improvement in Photon Storage Fidelities Using Subradiance and “Selective Radiance” in Atomic Arrays

A central goal within quantum optics is to realize efficient, controlled interactions between photons and atomic media. A fundamental limit in nearly all applications based on such systems arises
