Feshbach resonances are the essential tool to control the interaction between atoms in
ultracold quantum gases. They have found numerous experimental applications, opening up …

In this review, we discuss the properties of a few impurity atoms immersed in a gas of
ultracold fermions—the so-called Fermi polaron problem. On one hand, this many-body …

An overview of the physics of spinor and dipolar Bose–Einstein condensates (BECs) is
given. Mean-field ground states, Bogoliubov spectra, and many-body ground and excited …

This paper presents a review of the current state of the art in the research field of cold and
ultracold molecules. It serves as an introduction to the focus issue ofNew Journal of Physics …

Recent experimental and theoretical progress has elucidated the tunable crossover, in
ultracold Fermi gases, from BCS-type superconductors to BEC-type superfluids. The BCS …

The physics of quantum degenerate atomic Fermi gases in uniform as well as in
harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is …

The control of physical systems and their dynamics on the level of individual quanta
underpins both fundamental science and quantum technologies. Trapped atomic and …

This paper summarizes the experimental frontier of ultracold fermionic gases. It is based on
three lectures which one of the authors gave at the Varenna Summer School describing the …

Atomic gases confined in curved geometries are characterized by distinctive features that
are absent in their flat counterparts, such as periodic boundaries, local curvature and …

The recent experimental realization of strongly imbalanced mixtures of ultracold atoms
opens new possibilities for studying impurity dynamics in a controlled setting. In this paper …
