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 …

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 …

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 …

We study the impact of three-body physics in quenched unitary Bose gases, focusing on the
role of the Efimov effect. Using a local density model, we solve the three-body problem and …

The properties of cold Bose gases at unitarity have been extensively investigated in the last
few years both theoretically and experimentally. In this Letter we use a family of interactions …

We renormalize the two-body contact interaction based on the exact solution of two
interacting particles in a harmonic trap. This renormalization extends the validity of the …

Recent advances in rapidly quenched ultracold atomic Fermi gases near a Feshbach
resonance have brought about a number of interesting problems in the context of observing …

This thesis describes studies of out-of-equilibrium dynamics in an interacting homogeneous
Bose gas. We use the versatile platform of an ultracold gas of 39 K, prepared in an optical …

Recent advances in the tunability of ultracold atomic gases have created opportunities for
studying interesting quantum many-body systems. Fano-Feshbach resonances, in particular …

This thesis investigates two topics: ultracold atomic collisions in a radio-frequency field and
universal properties of a degenerate unitary Bose gas. One interesting point of the unitary …
