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 …

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 …

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 …

We present, and derive analytic expressions for, a fundamental limit to the sympathetic
cooling of ions in radio-frequency traps using cold atoms. The limit arises from the work …

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 …

Classical collisions with an ideal gas generate non-Maxwellian distribution functions for a
single ion in a radio frequency ion trap. The distributions have power-law tails whose …

Multipole radiofrequency ion traps are a highly versatile tool to study molecular ions and
their interactions in a well-controllable environment. In particular the cryogenic 22-pole ion …

In mixed systems of trapped ions and cold atoms, the ions and atoms can coexist at different
temperatures. This is primarily due to their different trap** and cooling mechanisms. The …
