Quantum atomic and molecular gases are flexible systems for studies of fundamental many-
body physics. They have traditionally been produced in harmonic electromagnetic traps and …

This paper reviews recent experimental and theoretical progress concerning many-body
phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling …

We have observed the Bose-Einstein condensation of an atomic gas in the (quasi) uniform
three-dimensional potential of an optical box trap. Condensation is seen in the bimodal …

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 …

Abstract The Kibble–Zurek mechanism is a theoretical framework that describes the
formation and scaling of topological defects in symmetry-breaking phase transitions. It was …

This article reviews theoretical and experimental developments for one-dimensional Fermi
gases. Specifically, the experimentally realized two-component delta-function interacting …

An open quantum system, the time evolution of which is governed by a master equation, can
be driven into a given pure quantum state by an appropriate design of the coupling between …

The Fermi-Hubbard model is a key concept in condensed matter physics and provides
crucial insights into electronic and magnetic properties of materials. Yet, the intricate nature …

In the course of a nonequilibrium continuous phase transition, the dynamics ceases to be
adiabatic in the vicinity of the critical point as a result of the critical slowing down (the …

Kibble-Zurek theory models the dynamics of spontaneous symmetry breaking, which plays
an important role in a wide variety of physical contexts, ranging from cosmology to …
