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 …

We review the recent theoretical and experimental progress regarding the generalized
hydrodynamics (GHD) behavior of the one-dimensional (1D) Bose gas with contact …

This paper presents a review of the current state of the art in the research field of cold and
ultracold molecules. It serves as an introduction to the focus issue ofNew Journal of Physics …

This article reviews theoretical and experimental developments for one-dimensional Fermi
gases. Specifically, the experimentally realized two-component delta-function interacting …

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 …

Under certain circumstances, three or more interacting particles may form bound states.
Although the general few-body problem is not analytically solvable, the so-called Efimov …
