Since Dicke's seminal paper on coherence in spontaneous radiation by atomic ensembles,
superradiance has been extensively studied. Subradiance, on the contrary, has remained …

Superradiance has been extensively studied in the 1970s and 1980s in the regime of
superfluorescence, where a large number of atoms are initially excited. Cooperative …

We report direct, time-resolved observations of single-photon superradiance in a highly
extended, elliptical sample of cold Rb 87 atoms. The observed rapid decay rate is …

Cooperative scattering has been the subject of intense research in the last years. In this
article, we discuss the concept of cooperative scattering from a broad perspective. We briefly …

Dicke superradiance has been observed in many systems and is based on constructive
interferences between many scattered waves. The counterpart of this enhanced dynamics …

We study numerically the spectrum of the non-Hermitian effective Hamiltonian that describes
the dipolar interaction of a gas of N≫ 1 atoms with the radiation field. We analyze the …

Results from higher order mean-field calculations of light interacting with atom arrays are
presented for calculations of one-and two-time expectation values. The atoms are …

A cloud of cold N two‐level atoms driven by a resonant laser beam shows cooperative
effects both in the scattered radiation field and in the radiation pressure force acting on the …

In recent experiments, a novel type of cascaded quantum system has been realized using
nanofiber-coupled cold atomic ensembles. This setup has enabled the study of superradiant …

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) …
