Query: Ultracold atoms out of equilibrium   The relaxation of isolated quantum many-body systems is a major unsolved
problem connecting statistical and quantum physics. Studying such relaxation
processes remains a challenge despite considerable efforts. Experimentally, it
requires the creation and manipulation of well-controlled and truly isolated
quantum systems. In this context, ultracold neutral atoms provide unique
opportunities to understand non-equilibrium phenomena because of the large set
of available methods to isolate, manipulate and probe these systems. Here, we
give an overview of the rapid experimental progress that has been made in the
field over the last years and highlight some of the questions which may be
explored in the future.
