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 …

Gauge fields are central in our modern understanding of physics at all scales. At the highest
energy scales known, the microscopic universe is governed by particles interacting with …

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

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 …

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 …

We observe two consecutive heteronuclear Efimov resonances in an ultracold Li-Cs mixture
by measuring three-body loss coefficients as a function of magnetic field near a Feshbach …

In few-body physics, Efimov states are an infinite series of three-body bound states that obey
universal discrete scaling symmetry when pairwise interactions are resonantly enhanced …

We report on the observation of triatomic Efimov resonances in an ultracold gas of cesium
atoms. Exploiting the wide tunability of interactions resulting from three broad Feshbach …

Few-body physics has played a prominent role in atomic, molecular and nuclear physics
since the early days of quantum mechanics. It is now possible—thanks to tremendous …

Understanding and controlling collisions is crucial to the burgeoning field of ultracold
molecules. All experiments so far have observed fast loss of molecules from the trap …
