Hybrid systems of laser-cooled trapped ions and ultracold atoms combined in a single
experimental setup have recently emerged as a new platform for fundamental research in …

Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

Improved control of the motional and internal quantum states of ultracold neutral atoms and
ions has opened intriguing possibilities for quantum simulation and quantum computation …

We investigate the interaction of a laser-cooled trapped ion (Ba+ or Rb+) with an optically
confined Rb 87 Bose-Einstein condensate. The system features interesting dynamics of the …

We study cold collisions between trapped ions and trapped atoms in the semiclassical
(Langevin) regime. Using Yb+ ions confined in a Paul trap and Yb atoms in a magneto …

Recent years have seen the emergence of a new generation of collision and cold-chemistry
experiments in which cold atoms and ions are brought into contact in a controlled way in …

We present a combined experimental and theoretical study of cold reactive collisions
between laser-cooled Ca+ ions and Rb atoms in an ion-atom hybrid trap. We observe rich …

Traditionally, chemical reactions have been investigated by tuning thermodynamic
parameters, such as temperature or pressure. More recently, laser or magnetic field control …

Photoassociation of molecules out of an ultracold gas was thefirst successful approach to
create a gas of molecules in the electronic ground state at translational temperatures in the …

In the last five years, a novel field of physics and chemistry has developed in which cold
trapped ions and ultracold atomic gases are brought into contact with each other. Combining …
