Pinpointing Feshbach resonances and testing Efimov universalities in
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 …

Bose polaron and the Efimov effect: A Gaussian-state approach
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 …

Bose-Einstein condensation of Efimovian triples in the unitary Bose gas
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 …

Cumulant theory of the unitary Bose gas: Prethermal and Efimovian dynamics
We study the quench of a degenerate ultracold Bose gas to the unitary regime, where
interactions are as strong as allowed by quantum mechanics. We lay the foundation of a …

Chemistry of a light impurity in a Bose-Einstein condensate
Similar to an electron in a solid, an impurity in an atomic Bose-Einstein condensate (BEC) is
dressed by excitations from the medium, forming a polaron quasiparticle with modified …

Phase diagram for strong-coupling Bose polarons
Important properties of complex quantum many-body systems and their phase diagrams can
often already be inferred from the impurity limit. The Bose polaron problem describing an …

Few-body correlations in two-dimensional Bose and Fermi ultracold mixtures
Few-body correlations emerging in two-dimensional harmonically trapped mixtures, are
comprehensively investigated. The presence of the trap leads to the formation of atom-dimer …

Interferometry of Efimov states in thermal gases by modulated magnetic fields
We demonstrate that an interferometer based on modulated magnetic field pulses enables
precise characterization of the energies and lifetimes of Efimov trimers irrespective of the …
