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

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 …

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 …

A powerful set of universal relations, centered on a quantity called the contact, connects the
strength of short-range two-body correlations to the thermodynamics of a many-body system …

We observe two consecutive heteronuclear Efimov resonances in an ultracold Li-Cs mixture
by measuring three-body loss coefficients as a function of magnetic field near a Feshbach …

We investigate the zero-temperature properties of an impurity particle interacting with a Bose-
Einstein condensate (BEC), using a variational wave function that includes up to two …

We derive exact general relations between various observables for N spin-1/2 fermions with
zero-range or short-range interactions, in continuous space or on a lattice, in two or three …

In few-body physics, Efimov states are an infinite series of three-body bound states that obey
universal discrete scaling symmetry when pairwise interactions are resonantly enhanced …
