We study three-body recombination of Ba++ Rb+ Rb in the mK regime where a single Ba
138+ ion in a Paul trap is immersed into a cloud of ultracold Rb 87 atoms. We measure the …

Three-body recombination in physical chemistry

M Mirahmadi, J Pérez-Ríos - International Reviews in Physical …, 2022‏ - Taylor & Francis
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 …

Cold chemistry: a few-body perspective on impurity physics of a single ion in an ultracold bath

J Pérez-Ríos - Molecular Physics, 2021‏ - Taylor & Francis
Impurity physics is a traditional topic in condensed matter physics that nowadays is being
