The dependent scattering effect (DSE), which arises from the wave nature of
electromagnetic radiation, is a critical mechanism affecting the radiative properties of …

Dipole-dipole interactions are at the origin of long-lived collective atomic states, often called
subradiant, which are explored for their potential use in novel photonic devices or in …

We study the subradiant collective states of a periodic chain of two-level atoms with either
transversal or longitudinal transition dipole moments with respect to the chain axis. We show …

Atomic planar arrays offer a novel emerging quantum-optical many-body system in which
light mediates strong interactions between the atoms. The regular lattice structure provides a …

We experimentally and numerically study the temporal dynamics of light scattered by large
clouds of cold atoms after the exciting laser is switched off, in the low intensity (linear-optics) …

Modulation of scattering in random lasers (RLs) by magnetic fields has attracted much
attention due to its rich physical insights. We fabricate magnetic gain polymer optical fiber to …

Single atoms in dipole microtraps or optical tweezers have recently become a promising
platform for quantum computing and simulation. Here we report a detailed theoretical …

We present an optical picture of linear-optics superradiance, based on a single scattering
event embedded in a dispersive effective medium composed by the other atoms. This linear …

We study experimentally and theoretically the time-dependent response of a cold atom
cloud illuminated by a laser beam immediately after the light is switched on. We show that …

Ordered atomic arrays trapped in the vicinity of nanoscale waveguides offer original light-
matter interfaces, with applications to quantum information and quantum nonlinear optics …
