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

The study of open quantum systems–microscopic systems exhibiting quantum coherence
that are coupled to their environment–has become increasingly important in the past years …

This article reviews theoretical and experimental advances in Efimov physics, an array of
quantum few-body and many-body phenomena arising for particles interacting via short …

Systems consisting of few interacting fermions are the building blocks of matter, with atoms
and nuclei being the most prominent examples. We have created a few-body quantum …

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

We review recent experimental and theoretical progress on ultracold alkaline-earth Fermi
gases with emergent SU (N) symmetry. Emphasis is placed on describing the ground …

After decades of improvements in cooling techniques of several atomic species and in
finding methods for the achievement of stable quantum mixtures, the field is now ready for …

A recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

Abstract In 1970, Vitaly Efimov predicted that three quantum particles subjected to a
resonant pair-wise interaction can join into an infinite number of loosely bound states, even …

We study a system of two distinguishable fermions in a 1D harmonic potential. This system
has the exceptional property that there is an analytic solution for arbitrary values of the …
