The atom-ion hybrid system provides us with new platform to study ultracold collisions and chemical reactions, which play important role in quantum simulations, quantum information processing utilizing atom-ion interactions. To investigate chemical reactions in an ultracold regime, we start with neutral atoms trapped in an optical dipole trap and ions in a linear Paul trap, and combine them together to construct a hybrid system. Here we introduce our recent work on ultracold elastic/inelastic collisions at a single atom level with a state-by-state manner in our atom-ion hybrid system. From the quantitative discussion on the collision cross sections, the microscopic collisional mechanisms have been clarified.
