This review describes the emerging field of waveguide quantum electrodynamics concerned
with the interaction of photons propagating in a waveguide with localized quantum emitters …

An ensemble of emitters can behave very differently from its individual constituents when
they interact coherently via a common light field. After excitation of such an ensemble …

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 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 …

The dependent scattering effect (DSE), which arises from the wave nature of
electromagnetic radiation, is a critical mechanism affecting the radiative properties of …

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 …

Overcoming the detrimental effect of disorder at the nanoscale is very hard since disorder
induces localization and an exponential suppression of transport efficiency. Here we unveil …

It is interesting to observe that all optical materials with a positive refractive index have a
value of index that is of order unity. Surprisingly, though, a deep understanding of the …

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 …

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 …
