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 …

Effective field theory allows for a systematic and model-independent derivation of the forces
between nucleons in harmony with the symmetries of quantum chromodynamics. The …

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 …

This article provides an overview of the basic principles of the physics of quantum halo
systems, defined as bound states of clusters of particles with a radius extending well into …

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 …

Heavy-quark symmetry as applied to heavy hadron systems implies that their interactions
are independent of their heavy-quark spin (heavy-quark spin symmetry) and heavy flavor …

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 …

The adiabatic hyperspherical method is used to investigate the spectrum of the helium trimer
and to explore effects on the spectrum of varying the helium masses as well as the …

The theoretical status on universal aspects of weakly-bound neutron-rich light nuclei are
reviewed, considering few-body approaches. We focus the review on the low-energy …
