  • Controlling chemistry at the single-collision level is one of the main goals of experiments at ultralow temperatures. A method based on quantum logic techniques has now been shown to detect inelastic collisions in a hybrid ion–atom platform.

  • Observing spin-changing atom–molecule collisions with quantum-state precision provides clues of short-range interactions. Now it is shown that the outcomes of the KRb + Rb collision only align with a statistical model after assuming the non-conservation of mechanical angular momentum. The observations also contradict coupled-channel calculations that neglect vibrations and conical intersections.

  • Studies on reactions between cold molecular ions and neutral atoms provide insights into intermolecular interactions. Here the authors explore the kinetics and dynamics of charge-transfer collisions between the cold N\({}_{2}^{+}\) and O\({}_{2}^{+}\) ions and neutral Rb atoms and discuss the role of long- and short-range effects.

  • Magnetically tunable interactions between lithium atoms and barium ions are used to demonstrate and probe Feshbach resonances between atoms and ions, which could have applications in the fields of experimental quantum simulation and fundamental physics.
