Understanding relaxation processes is an important unsolved problem in many areas of
physics. A key challenge is the scarcity of experimental tools for the characterization of …

We review recent developments in the physics of ultracold atomic and molecular gases in
optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard …

Interference with atomic and molecular matter waves is a rich branch of atomic physics and
quantum optics. It started with atom diffraction from crystal surfaces and the separated …

We review the recent progress in the understanding of the relaxation of isolated near-
integrable quantum many-body systems. Focusing on prethermalization and universal …

Low-dimensional systems provide beautiful examples of many-body quantum physics. For
one-dimensional (1D) systems, the Luttinger liquid approach provides insight into universal …

Particle-wave duality enables the construction of interferometers for matter waves, which
complement optical interferometers in precision measurement devices. This requires the …

We review the experimental realization of a single bosonic Josephson junction for ultracold
gases, which was made possible by the generation of a precisely controllable double-well …
