Photon-photon scattering in vacuum is extremely weak. However, strong effective
interactions between single photons can be realized by employing strong light-matter …

Versatile interfaces with strong and tunable light–matter interactions are essential for
quantum science because they enable map** of quantum properties between light and …

Enhancing the optical cross section is an enticing goal in light-matter interactions, due to its
fundamental role in quantum and nonlinear optics. Here, we show how dipolar interactions …

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 …

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 …

Recent work has shown that collective single photon emission from an ensemble of
resonate two-level atoms, ie, single photon superradiance, is a rich field of study. The …

Ultracold atomic systems are among the most promising platforms that have the potential to
shed light on the complex behavior of many-body quantum systems. One prominent …

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 experimentally study resonant light scattering by a one-dimensional randomly filled
chain of cold two-level atoms. By a local measurement of the light scattered along the chain …
