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 investigate the properties of a spinless Fermi gas close to ap-wave interaction
resonance. We show that the effects of interaction near ap-wave resonance are captured by …

Scale invariance plays an important role in unitary Fermi gases. Discrete scaling symmetry
manifests itself in quantum few-body systems such as the Efimov effect. Here, we report on …

We investigate droplet formation in three-component ultracold bosons. In particular, we
identify the formation of a Borromean droplet, where only the ternary bosons can form a self …

We experimentally investigate the unitarity-limited behavior of the three-body loss near ap-
wave Feshbach resonance in a single-component Fermi gas of Li 6 atoms. At the unitarity …

The contact is an important concept that characterizes the universal properties of a strongly
interacting quantum gas. It appears in both thermodynamic (energy, pressure, etc.) and …

We describe the three-body loss coefficient of identical fermions with p-wave interactions
using a set of rate equations in which three-body recombination happens via an indirect …

We consider the system of three nonrelativistic spinless fermions in two dimensions, which
interact through spherically-symmetric pair interactions. Recently, a claim has been made by …

Few-body correlations emerging in two-dimensional harmonically trapped mixtures, are
comprehensively investigated. The presence of the trap leads to the formation of atom-dimer …
