Kinetics of a single trapped ion in an ultracold buffer gas
Christoph Zipkes, Lothar Ratschbacher, Carlo Sias +1
The immersion of a single ion confined by a radiofrequency trap in an ultracold atomic gas extends the concept of buffer gas cooling to a new temperature regime. The steady state e…
Hybrid quantum systems of atoms and ions
Christoph Zipkes, Lothar Ratschbacher, Stefan Palzer +2
In recent years, ultracold atoms have emerged as an exceptionally controllable experimental system to investigate fundamental physics, ranging from quantum information science to s…
Cold heteronuclear atom-ion collisions
Christoph Zipkes, Stefan Palzer, Lothar Ratschbacher +2
We study cold heteronuclear atom ion collisions by immersing a trapped single ion into an ultracold atomic cloud. Using ultracold atoms as reaction targets, our measurement is sens…
