We propose metasurface holograms as a novel platform to generate optical trap arrays for
cold atoms with high quality, efficiency, and thermal stability. We developed design and …

In inverted atomic ensembles, photon-mediated interactions give rise to Dicke
superradiance, a form of many-body decay that results in a rapid release of energy as a …

Fully inverted atoms placed at exactly the same location synchronize as they deexcite, and
light is emitted in a burst (known as “Dicke's superradiance”). We investigate the role of finite …

We report the observation of subradiance in dense ensembles of cold Rb 87 atoms
operating near Dicke's regime of a large number of atoms in a volume with dimensions …

Quantum emitters coupled to optical resonators are quintessential systems for exploring
fundamental phenomena in cavity quantum electrodynamics (cQED) and are commonly …

The collective absorption and emission of light by an ensemble of atoms is at the heart of
many fundamental quantum optical effects and the basis for numerous applications …

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 …

Atomic planar arrays offer a novel emerging quantum-optical many-body system in which
light mediates strong interactions between the atoms. The regular lattice structure provides a …

At the quantum many-body level, atom-light interfaces generally remain challenging to solve
for or understand in a nonperturbative fashion. Here we consider a waveguide quantum …

The deterministic generation of multiexcitation subradiant states proves to be challenging.
Here, we present a viable path towards their transient generation in finite-sized ordered …
