The foundation of atomic physics is the arsenal of spectroscopic tools to probe individual
atoms and molecules with astounding precision. With the advent of ultracold quantum …

Physical systems characterized by a shallow two-body bound or virtual state are governed at
large distances by continuous scale invariance, which is broken into discrete scale …

Understanding strongly correlated phases of matter, such as the quark–gluon plasma and
neutron stars, and in particular the dynamics of such systems, for example, following a …

In recent years, there has been notable progress in the preparation and control of ultracold
gases of diatomic molecules. The next experimental challenge is the production of ultracold …

We consider the ground-state properties of an impurity particle (“polaron”) resonantly
interacting with a Bose-Einstein condensate (BEC). Focusing on the equal-mass system, we …

Using a combination of bound-state spectroscopy and loss spectroscopy, we pinpoint eight
intrastate Feshbach resonances in K 39, as well as six previously unexplored interstate …

Since the Efimov effect was introduced, a detailed theoretical understanding of Efimov
physics has been developed in the few-body context. However, it has proven challenging to …

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

In an atomic Bose-Einstein condensate quenched to the unitary regime, we predict the
sequential formation of a significant fraction of condensed pairs and triples. At short …

We study the dynamics of an initially degenerate homogeneous Bose gas after an
interaction quench to the unitary regime at a magnetic Feshbach resonance. As the cloud …
