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 …

Particles with short-range interactions and a large scattering length have universal low-
energy properties that do not depend on the details of their structure or their interactions at …

Quantum theory dictates that upon weakening the two-body interaction in a three-body
system, an infinite number of three-body bound states of a huge spatial extent emerge just …

The quantum mechanical three-body problem is studied for general short-range interactions.
We work in coordinate space to facilitate accurate computations of weakly bound and …

We identify two qualitatively different mechanisms that control three-body recombination in a
spin-polarized gas near zero temperature. A universal curve describes the recombination …

A molecular beam consisting of small helium clusters is diffracted from a 100 nm period
transmission grating. The relative dimer intensities have been measured out to the 7th order …

We review topics of current interest in the physics of electronic, atomic and molecular
scattering in the vicinity of thresholds. Starting from phase space arguments, we discuss the …

One of characteristic phenomena for nuclei beyond the proton dripline is the simultaneous
emission of two protons (2p). The current status of our knowledge of this most recently …

The dissociative recombination of an H 3+ ion after it is struck by a low-energy electron is
important for understanding observations of H 3+ in diffuse interstellar clouds. At the same …
