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 …

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 …

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 …

Background: In recent years properties of light rare isotopes have been measured with high
accuracy. At the same time, the theoretical description of light nuclei has made enormous …

The universal properties and structure of halo nuclei composed of two neutrons (2 n) and a
core are investigated within an effective quantum mechanics framework. We construct an …

The Efimov phenomenon manifests itself as an emergent discrete scaling symmetry in the
quantum three-body problem. In the unitarity limit, it leads to an infinite tower of three-body …

The recently extracted matter radius of carbon isotope 22C allows us to estimate the mean-
square distance of a halo neutron with respect to the center-of-mass of this nucleus. By …

An effective field theory developed for systems interacting through short-range interactions
can be applied to systems of cold atoms with a large scattering length and to nucleons at low …

The emergence of Efimov levels in a three-body system is investigated near the unitarity limit
characterized by a resonant two-body interaction. No direct evidence of Efimov levels is …
