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 …

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 …

Understanding strongly correlated phases of matter, such as the quark–gluon plasma and
neutron stars, and in particular the dynamics of such systems, for example, following a …

From neutron stars to high-temperature superconductors, strongly interacting many-body
systems at or near quantum degeneracy are a rich source of intriguing phenomena. The …

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 the observation of a three-body recombination resonance in an ultracold gas of
cesium atoms at a very large negative value of the s-wave scattering length. The resonance …

In many-body systems governed by pairwise contact interactions, a wide range of
observables is linked by a single parameter, the two-body contact, which quantifies two …

Using a combination of bound-state spectroscopy and loss spectroscopy, we pinpoint eight
intrastate Feshbach resonances in K 39, as well as six previously unexplored interstate …

We provide a general discussion on the importance of three-body Efimov physics for
strongly interacting ultracold quantum gases. Using the adiabatic hyperspherical …
