Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the
experimental investigation of ultracold gases made of highly magnetic atoms has …

We show that induced dipole-dipole interactions allow for photon blockade in
subwavelength ensembles of two-level, ground-state neutral atoms. Our protocol relies on …

Controlling ultracold atoms with laser light has greatly advanced quantum science. The
wavelength of light sets a typical length scale for most experiments to the order of 500 …

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 …

Optical tweezers have become essential tools to manipulate atoms or molecules at a single
particle level. However, using standard diffraction-limited optical systems, the transverse …

Quantum emitters coupled to a waveguide are a paradigm of quantum optics, whose
essential properties are described by waveguide quantum electrodynamics (QED). We study …

In cold atomic systems, fast and high-resolution microscopy of individual atoms is crucial,
since it can provide direct information on the dynamics and correlations of the system. Here …

Recent experiments demonstrated deeply subwavelength lattices using atoms with N
internal states Raman coupled with lasers of wavelength λ. The resulting unit cell was λ/2 N …

We examine topological phases and symmetry-protected electronic edge states in the
context of a Rydberg composite: a Rydberg atom interfaced with a structured arrangement of …

We investigate two-color photon correlations in the light emitted by two strongly driven,
strongly interacting two-level emitters. The correlations are interpreted introducing the …
