We establish the concept of topological pum** in one-dimensional systems with long-
range couplings and apply it to the transport of a photon in quantum optical systems. In our …

We theoretically and computationally investigate the role that the spatial spread of atoms
plays in the transmission and reflection of weak light from atom arrays. In particular, we …

Subwavelength arrays of quantum emitters offer an efficient free-space approach to
coherent light-matter interfacing, using ultracold atoms or two-dimensional solid-state …

We propose a new expression of the cooperative decay rate of a one-dimensional chain of
N two-level atoms in the single-excitation configuration. From it, the interference nature of …

Arrays of coupled dipole emitters support collective single-and multiphoton states that can
preserve quantum excitations. One of the crucial characteristics of these states is the lifetime …

Atomic arrays have emerged as an interesting light-matter platform displaying strong and
controllable collective effects. In subwavelength regimes, they are characterized by a …

Atomic arrays provide an important quantum optical platform with photon-mediated dipole–
dipole interactions that can be engineered to realize key applications in quantum …

Ensembles of dipolar emitters which couple collectively to the radiation field display sub-and
superradiance. These terms refer to a reduction or an enhancement of photon emission …

The idea of making photons effectively interact has attracted a lot of interest in recent years,
for several reasons. Firstly, since photons do not naturally interact with each other, it is of …
