Circuit quantum electrodynamics is one of the most promising platforms for efficient quantum
simulation and computation. In recent groundbreaking experiments, the immense flexibility …

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 …

Quantum-computation architecture based on d-level systems, or qudits, has attracted
considerable attention recently due to their enlarged Hilbert space. Extensive theoretical …

Photon-mediated interactions within an excited ensemble of emitters can result in Dicke
superradiance, where the emission rate is greatly enhanced, manifesting as a high-intensity …

The optical properties of subwavelength arrays of atoms or other quantum emitters have
attracted significant interest recently. For example, the strong constructive or destructive …

We measure the coherent scattering of low-intensity, near-resonant light by a cloud of laser-
cooled two-level rubidium atoms with a size comparable to the wavelength of light. We …

We present a model describing the transmission of light through atomic media with a
vanishing index of refraction. Zero-index materials are of particular interest as the infinite …

Dipole-dipole interactions lead to frequency shifts that are expected to limit the performance
of next-generation atomic clocks. In this work, we compute dipolar frequency shifts …

We investigate the driven-dissipative dynamics of multilevel atomic arrays interacting via
dipolar interactions at subwavelength spacings. Unlike two-level atoms in the weakly excited …

Open quantum systems with chiral interactions can be realized by coupling atoms to guided
radiation modes in photonic waveguides or optical fibers. In their steady state these systems …
