The atom-ion hybrid system provides a new platform to study ultracold collisions and chemical reactions.
To investigate chemical reactions in ultracold regimes, we combine neutral atoms in an optical
trap and ions in a Paul trap to construct an atom-ion hybrid system. Here we introduce our recent work
on ultracold elastic/inelastic collisions at a single atom level with a state-by-state manner. From quantitative
discussions on the collision’s cross-sections, we clarified the microscopic collisional mechanisms.
