Positronium (Ps) is an exotic hydrogenic atom composed of an electron bound to a positron
via the Coulomb force. Being composed of two low-mass leptons, positronium is, for all …

Ultracold atoms, molecules and ions provide a unique playground to explore chemistry at
ultracold temperatures. In this Review, we discuss what makes these systems particularly …

The structure and dynamics of a molecular system is governed by its potential energy
surface (PES), representing the total energy as a function of the nuclear coordinates …

Ultracold quantum gases confined in three-dimensional bubble traps are promising tools for
exploring many-body effects on curved manifolds. As an alternative to the conventional …

We measure chemical reactions between a single trapped Yb+ 174 ion and ultracold Li 2
dimers. This produces LiYb+ molecular ions that we detect via mass spectrometry. We …

Motivated by the recent experimental realization of ultracold quantum gases in shell
topology, we propose a straightforward implementation of matter-wave lensing techniques …

We theoretically investigate the trap-assisted formation of complexes in atom-ion collisions
and their impact on the stability of the trapped ion. The time-dependent potential of the Paul …

The present Letter shows that the formation of ozone in ternary collisions O+ O 2+ M—the
primary mechanism of ozone formation in the stratosphere—at temperatures below 200 K …

Three-body recombination, or ternary association, is a termolecular reaction in which three
particles collide, forming a bound state between two, whereas the third escapes freely …

Impurity physics is a traditional topic in condensed matter physics that nowadays is being
explored in the field of ultracold gases. Among the different classes of impurities, we focus …
