We propose metasurface holograms as a novel platform to generate optical trap arrays for
cold atoms with high quality, efficiency, and thermal stability. We developed design and …

Our experience of the world around us is governed almost entirely by light–matter
interactions. At the most fundamental level, such interactions are described by quantum …

Superconducting qubits in a waveguide have long-range interactions mediated by photons
that cause the emergence of collective states. Destructive interference between the qubits …

In quantum optics, it is common to assume that atoms are pointlike objects compared to the
wavelength of the electromagnetic field they interact with. However, this dipole …

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 …

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 …

Ordered atomic arrays with subwavelength spacing have emerged as an efficient and
versatile light-matter interface, where collective interactions give rise to sets of super-and …

Subradiant states in a finite chain of two-level quantum emitters coupled to a one-
dimensional reservoir are a resource for superior photon storage and their controlled …

Superradiance and subradiance are collective effects that emerge from coherent
interactions between quantum emitters. Due to their many-body nature, theoretical studies of …

We present two different methods for modeling non-Markovian quantum light-matter
interactions in waveguide QED systems, using matrix product states (MPSs) and a space …
