Abstract Total internal reflection (TIR) governs the guiding mechanisms of almost all dielectric waveguides and therefore constrains most of the light in the material with the highest refractive index. The few options available to access the properti

We study weak pulse propagation through near-resonant collective media. The timescales of the pulse and the lifetime of the media are comparable. The transmitted pulse develops temporal oscillations, known as dynamical beats. We use a collection of ^

Dicke superradiance is an important collective quantum phenomenon, but its analysis is hindered by the exponential growth of the state space with atom number. Here, the authors develop a theoretical framework that overcomes this, and predict a critic

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 if there is one—or just a few—dominant decay channels. For a fixed atom number

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 modes that do not decay into free space. We show that these modes can be

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 of a collective excitation is reduced or enhanced due to correlated int

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 burst at short times. The superradiant burst is most commonly observed

We propose metasurface holograms as a novel platform to generate optical trap arrays for cold atoms with high fidelity, efficiency, and thermal stability. We developed design and fabrication methodologies to create dielectric, phase-only metasurface
