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 …

In recent years extensive theoretical and experimental studies of universal few-body physics
have advanced our understanding of universal Efimov physics. Whereas theory had been …

The low-energy spectrum of three particles interacting via nearly resonant two-body
interactions in the Efimov regime is set by the so-called three-body parameter. We show that …

The problem of three interacting quantal bodies, in its various guises, seems deceptively
simple, but it has also provided striking surprises, such as the Efimov effect,, which was …

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 …

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 …

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 …

Ultracold atomic gases have developed into prime systems for experimental studies of
Efimov three-body physics and related few-body phenomena, which occur in the universal …

Abstract Systems of three interacting particles are notorious for their complex physical
behaviour. A landmark theoretical result in few-body quantum physics is Efimov's prediction …
