Temat Ultracold ion-atom collisions in the quantum regime
Abstrakt 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. 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 and Stuttgart we have overcome this limitation and how electronic structure theory and nuclear dynamics simulations guided and explained experimental efforts.
