The understanding of disordered quantum systems is still far from being complete, despite
many decades of research on a variety of physical systems. In this review we discuss how …

Coherent effects manifested in light scattering from cold, optically dense and disordered
atomic systems are reviewed from a primarily theoretical point of view. Development of the …

We study quantum transport of an interacting Bose-Einstein condensate in a two-
dimensional disorder potential. In the limit of a vanishing atom-atom interaction, a sharp …

We present an overview of the investigations on the transport of near-resonant light in laser-
cooled atomic vapors, a field that emerged during the past decade. We first discuss time …

We review experimental and theoretical studies of coherent backscattering of near resonant
radiation from an ultracold atomic gas in the weak localization regime. Recent …

We outline the nonperturbative theory of multiple scattering of resonant, intense laser light
off a dilute cloud of cold atoms. A combination of master equation and diagrammatic …

Chaos implies unpredictability, fluctuations, and the need for statistical modelling. Quantum
optics has developed into one of the most advanced subdisciplines of modern physics in …

Light scattered by a regular structure of atoms can exhibit interference signatures, similar to
the classical double-slit. These first-order interferences, however, vanish for strong light …

In this theoretical paper, we investigate coherence properties of the near-resonant light
scattered by two atoms exposed to a strong monochromatic field. To properly incorporate …

We give a detailed derivation of the master-equation description of the coherent
backscattering of laser light by cold atoms. In particular, our formalism accounts for the …
