A central goal within quantum optics is to realize efficient, controlled interactions between
photons and atomic media. A fundamental limit in nearly all applications based on such …

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 …

Quantum cooperativity is evident in light-matter platforms where quantum-emitter ensembles
are interfaced with confined optical modes and are coupled via the ubiquitous …

Atoms interact with each other through the electromagnetic field, creating collective states
that can radiate faster or slower than a single atom, ie, super-and sub-radiance. When the …

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 …

The properties of coupled emitters can differ dramatically from those of their individual
constituents. Canonical examples include sub-and super-radiance, wherein the decay rate …

Atom arrays are a new type of quantum light-matter interface. Here we propose to employ
one-dimensional ordered arrays as atomic waveguides. These arrays support optical guided …

We investigate the collective decay dynamics of atoms with a generic multilevel structure
(angular momenta F↔ F′) coupled to two light modes of different polarization inside a …

A major application for atomic ensembles consists of a quantum memory for light, in which
an optical state can be reversibly converted to a collective atomic excitation on demand …

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 …
