Ultracold physics and cold chemistry
, 2022 This thesis studies single ions inside a radio-frequency trap interacting with ultracold neutral particles. During a collision, the ion can gain energy from the time-dependent trapping field, which limits the attainable collision energies. We mitigate this effects by using Yb+ ions and Li atoms, the elements with the largest ion-to-atom mass ratio that

State-to-state chemistry with ultracold neutral Rb atoms
, 2020 In this thesis, I report on experiments on the detection and the production of molecules in an ultracold atomic gas. These experiments can be divided into two main parts. The first part is about state-to-state experiments where chemical reaction products are detected in a quantum state resolved way. The second part is about Rydberg molecules.

A single ion immersed in an ultracold gas: from cold chemistry to impurity physics
Europhysics News, 2023 A single ion in an ultracold gas is a versatile experimental platform to study interactions between charged and neutral particles in a controllable manner. When the gas density is large enough, a single ion can be viewed as an impurity in a sea of ultracold atoms or molecules. On the other hand, that single ion can also undergo a chemical reaction with

In situ observation of chemistry in Rydberg molecules within a Bose-Einstein-condensate
Physical Review ResearchWe often infer the state of systems in nature indirectly, for example, in high-energy physics by the interaction of particles with an ambient medium. We adapt this principle to energies 9 orders of magnitude smaller, to classify the final state of exotic

MoleculesThree-body recombination reactions, in which two particles form a bound state while a third one bounces off after the collision, play significant roles in many fields, such as cold and ultracold chemistry, astrochemistry, atmospheric physics, and plasma ...
