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 …

This review examines the tendency of light nuclei to exhibit clustering, where correlations
between nucleons result in the formation of precipitates, typically α particles. The …

Feshbach resonances are the essential tool to control the interaction between atoms in
ultracold quantum gases. They have found numerous experimental applications, opening up …

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 …

It is often assumed that few-and many-body systems can be accurately described by
considering only pairwise two-body interactions of the constituents. We illustrate that three …

Nuclear halos emerge as new degrees of freedom near the neutron and proton driplines.
They consist of a core and one or a few nucleons which spend most of their time in the …

The variational method complemented with the use of explicitly correlated Gaussian basis
functions is one of the most powerful approaches currently used for calculating the …

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 …

We analyze the dynamics of Bose polarons in the vicinity of a Feshbach resonance between
the impurity and host atoms. We compute the radio-frequency absorption spectra for the …
