We resolve the unexpected and long-standing disagreement between experiment and
theory in the Efimovian three-body spectrum of Li 7, commonly referred to as the lithium few …

We study Efimov physics of three identical bosons with pairwise multichannel interactions for
Feshbach resonances of adjustable width in magnetic field. We find that the two-body …

We develop a full multichannel spin model in momentum space to investigate three-body
recombination of identical alkali-metal atoms colliding in a magnetic field. The model …

We study the three-body scattering hypervolume D of atoms whose scattering length a is on
the order of or smaller than the typical range r vdW of the van der Waals attraction. We find …

Quantifying the nonuniversal three-body losses in ultracold atomic gases has been a long-
standing problem. We go beyond earlier approaches to solve this problem by using a model …

We consider two identical fermions interacting in the p-wave channel. Each fermion also
interacts with another particle in the vicinity of an s-wave resonance. We find that in addition …

We investigate the prospects of combining a standard momentum space approach for
ultracold three-body scattering with efficient coordinate space schemes to solve the …

We study a degenerate Bose gas quenched to unitarity by solving a many-body model
including three-body losses and correlations up to second order. As the gas evolves in this …

We study three-body systems in a mass-imbalanced, two-component, cold-atom mixture,
and we investigate the three-body parameter of their Efimov states for both bosonic and …

A powerful experimental technique to study Efimov physics at positive scattering lengths is
demonstrated. We use the Feshbach dimers as a local reference for Efimov trimers by …
