Strontium optical lattice clocks have the potential to simultaneously interrogate millions of
atoms with a high spectroscopic quality factor of 4× 1017. Previously, atomic interactions …

Dicke superradiance is an example of emergence of macroscopic quantum coherence via
correlated dissipation. Starting from an initially incoherent state, a collection of excited atoms …

Coherent control of high–quality factor optical transitions in atoms has revolutionized
precision frequency metrology. Leading optical atomic clocks rely on the interrogation of …

We implement imaging spectroscopy of the optical clock transition of lattice-trapped
degenerate fermionic Sr in the Mott-insulating regime, combining micron spatial resolution …

Dicke superradiance in ordered atomic arrays is a phenomenon where atomic
synchronization gives rise to a burst in photon emission. This superradiant burst only occurs …

While artificially fabricated patterned metasurfaces are providing paradigm-shifting optical
components for classical light manipulation, strongly interacting, controllable, and …

Ordered atomic arrays with subwavelength spacing have emerged as an efficient and
versatile light-matter interface, where collective interactions give rise to sets of super-and …

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 …

Collective coupling between dipoles can dramatically modify the optical response of a
medium. Such effects depend strongly on the geometry of the medium and the polarization …

Dipole spin-wave states of atomic ensembles with wave vector k (ω) mismatched from the
dispersion relation of light are difficult to access by far-field excitation but may support rich …
