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 …

Laser frequency noise contributes a significant limitation to today's best atomic clocks. A
proposed solution to this problem is to create a superradiant laser using an optical clock …

We show how strong light-mediated resonant dipole-dipole interactions between atoms can
be utilized in a control and storage of light. The method is based on a high-fidelity …

We investigate collective emission from coherently driven ultracold 88Sr atoms. We perform
two sets of experiments using a strong and weak transition that are insensitive and sensitive …

We experimentally and theoretically investigate collective radiative effects in an ensemble of
cold atoms coupled to a single-mode optical nanofiber. Our analysis unveils the microscopic …

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 …

We measure the coherent scattering of light by a cloud of laser-cooled atoms with a size
comparable to the wavelength of light. By interfering a laser beam tuned near an atomic …

We investigate the existence of topological phases in a dense two-dimensional atomic
lattice gas. The coupling of the atoms to the radiation field gives rise to dissipation and a …

We show that two-time, second-order correlations of scattered photons from planar arrays
and chains of atoms display nonclassical features that can be described by a superatom …

We study the emergence of a collective optical response of a cold and dense Rb 87 atomic
cloud to a near-resonant low-intensity light when the atom number is gradually increased …
