In dimension three, a disordered quantum system may have a transition between a metallic/diffusive phase at low disorder and a isolating/localized phase at strong disorder. In the vicinity of this so-called Anderson transition, it is well known that

In a disordered potential, the diffusive transport of non-interacting particles can be inhib- ited, a phenomenon known as Anderson localization. In three dimensions, there exists a quantum phase-transition between localized (insulator) and diffusive

In solid state physics, the study of the effects of disorder led to the discovery of a phase transition. For weak disorder, the solid is a conductor, whereas for strong disorder it becomes an insulator. This is known as the "Anderson transition" or a

The localization of waves in non-periodic media is a universal phenomenon, occurring in a variety of different quantum and classical systems, including condensed-matter, Bose-Einstein condensates in optical lattices, quantum chaotic systems, sound wa

By submitting a cloud of cold caesium atoms to a periodically pulsed standing wave, we experimentally realized a quantum system presenting a dynamic that is chaotic in the classical limit called the Kicked Rotor. Such a system presents a phenomenon c
