Ordered atomic arrays with subwavelength lattice spacing emit light collectively. For fully
inverted atomic arrays, this results in an initial burst of radiation and a fast buildup of …

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

We analytically and numerically study collective emission from an ensemble of atoms in the
weak-excitation regime with the initial condition of uniform excitation of the ensemble. We …

We present a numerical study of the spatial coherence of light that is radiated from a dilute
ensemble of atoms. The spatial coherence is established as a result of the collective …

We analyze the scattering of light from dipolar emitters whose disordered positions exhibit
correlations induced by static, long-range dipole-dipole interactions. The quantum …

Recent advances in generating well controlled dense arrangements of individual atoms in
free space have generated interest in understanding how the extended nature of these …

We analyze the driven-dissipative dynamics of subwavelength periodic atomic arrays in free
space, where atoms interact via light-induced dipole-dipole interactions. We find that …

Until 1963, the concept of coherence of optical fields was limited to what is nowadays called
first-order coherence. In 1963, Roy J. Glauber generalised the notion of coherence by …
