Ultracold ion-atom collisions in the quantum regime - dr M. Tomza

#quantum #optics

Abstract:
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 quantum physics [1]. Reaching the ultracold s-wave quantum regime has been one of the most important challenges in this field for a long time. Unfortunately, the lowest attainable temperatures in experiments using the Paul ion trap are limited by the possible rf-field-induced heating related to the
micromotion. In my seminar, I will present how in collaboration with
experimental groups from Amsterdam [2] and Stuttgart [3] we have
overcome this limitation and how electronic structure theory and
nuclear dynamics simulations guided and explained experimental
efforts.
