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 …

After decades of improvements in cooling techniques of several atomic species and in
finding methods for the achievement of stable quantum mixtures, the field is now ready for …

We report on the formation of heteronuclear quantum droplets in an attractive bosonic
mixture of K 41 and Rb 87. We observe long-lived self-bound states, both in free space and …

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 …

Advancing our understanding of non-equilibrium phenomena in quantum many-body
systems remains one of the greatest challenges in physics. Here we report on the …

We report on the observation of magnetic Feshbach resonances in a Fermi-Fermi mixture of
ultracold atoms with extreme mass imbalance and on their unique p-wave dominated three …

We provide a general discussion on the importance of three-body Efimov physics for
strongly interacting ultracold quantum gases. Using the adiabatic hyperspherical …

We report on the realization of a Fermi-Fermi mixture of ultracold atoms that combines mass
imbalance, tunability, and collisional stability. In an optically trapped sample of Dy 161 and K …

We report on the production of a 41 K-87 Rb dual-species Bose–Einstein condensate with
tunable interspecies interaction and we study the mixture in the attractive regime; ie, for …

We study three-body loss in an ultracold mixture of a thermal Bose gas and a degenerate
Fermi gas. We find that at unitarity, where the interspecies scattering length diverges, the …
