In recent years, the ability of cold atom experiments to explore condensed-matter-related
questions has dramatically progressed. Transport experiments, in particular, have expanded …

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 …

We theoretically study a one-dimensional (1D) mutually incommensurate bichromatic lattice
system, which has been implemented in ultracold atoms to study quantum localization. It has …

In disordered media, quantum interference effects are expected to induce complete
suppression of electron conduction. The phenomenon, known as Anderson localization, has …

Anderson localization (AL) is a ubiquitous interference phenomenon in which waves fail to
propagate in a disordered medium. We observe three-dimensional AL of noninteracting …

In a mesoscopic conductor, electric resistance is detected even if the device is defect-free.
We engineered and studied a cold-atom analog of a mesoscopic conductor. It consists of a …

Anderson localisation—the inhibition of wave propagation in disordered media—is a
surprising interference phenomenon which is particularly intriguing in two-dimensional (2D) …

Dimension 2 is expected to be the lower critical dimension for Anderson localization in a
time-reversal-invariant disordered quantum system. Using an atomic quasiperiodic kicked …

The review deals with the physics of cold atomic gases in the presence of disorder. The
emphasis is on the theoretical developments, although several experiments are also briefly …

We report on the direct observation of coherent backscattering (CBS) of ultracold atoms in a
quasi-two-dimensional configuration. Launching atoms with a well-defined momentum in a …
