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 …

Particles with resonant short-range interactions have universal properties that do not
depend on the details of their structure or their interactions at short distances. In the three …

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 derive exact general relations between various observables for N spin-1/2 fermions with
zero-range or short-range interactions, in continuous space or on a lattice, in two or three …

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 …

We report on experimental evidence of universality in ultracold Li 7 atoms' three-body
recombination loss in the vicinity of a Feshbach resonance. We observe a recombination …

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 …

The field of few-body physics has originally been motivated by understanding nuclear
matter, but in the past few years ultracold gases with tunable interactions have emerged as …

Recent measurements of Efimov resonances for a number of ultracold atom species have
revealed an unexpected universality, in which three-body scattering properties are …
