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 …

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 …

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 …

As in quantum field theory, for some singular two-body potentials, the momentum-space
perturbative treatment of the three-dimensional quantum N-body problem is shown to exhibit …

We evidence the existence of a universal correlation between the binding energies of
successive four-boson bound states (tetramers), for large two-body scattering lengths (a) …

The experimental revolution in ultracold atomic gas physics over the past decades has
brought tremendous amounts of new insight to the world of degenerate quantum systems …

The parametric region in the plane defined by the ratios of the energies of the subsystems
and the three-body ground state, in which Efimov states can exist, is determined. We use a …
