Cold ion-atom interactions represent a rapidly evolving field that merges atomic physics, quantum chemistry and many-body dynamics. In ultracold environments, ions and neutral atoms engage in ...

A completely new kind of molecule has been made by combining an extremely cold ion and a super-sized atom. The unusual molecular bond between the two particles was thousands of times longer than those ...

When we think of ions, we usually think of single atoms that have lost or gained some electrons, but entire molecules can also become ions. Physicists now show that cold molecular ions can be created ...
