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 …

Superconductivity and superfluidity of fermionic and bosonic systems are remarkable many-
body quantum phenomena. In liquid helium and dilute gases, Bose and Fermi superfluidity …

Efimov trimers are exotic three-body quantum states that emerge from the different types of
three-body continua in the vicinity of two-atom Feshbach resonances. In particular, as the …

We explore, both experimentally and theoretically, the response of an elongated Bose-
Einstein condensate to modulated interactions. We identify two distinct regimes differing in …

We study the lifetime of a Bose gas at and around unitarity using a Feshbach resonance in
lithium 7. At unitarity, we measure the temperature dependence of the three-body decay …

We perform precise studies of two-and three-body interactions near an intermediate-strength
Feshbach resonance in K 39 at 33.5820 (14) G. Precise measurement of dimer binding …

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

We have measured the binding energy of 7 Li Feshbach molecules deep into the
nonuniversal regime by associating atoms in a Bose-Einstein condensate with a modulated …

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 …
