Negative ions

Co-trapping of negative and positive ions
In this project we are trying to co-trap negatively and positively charged ions and couple their motion. This research could add negatively charged ions to the quantum information toolbox and enable high-precision spectroscopy of negatively charged ions.
In a first step we aim to co-trap negatively charged deuterium atoms with positively charged beryllium, and use the beryllium ion to sympathetically cool the deuterium ions.

This project is performed by semester, summer, and master students exclusively. This unique setting gives students the opportunity to own the project and perform cutting-edge research in an independent fashion.
This work is funded by an SNSF Spark grant and is lead independently by Daniel Kienzler. Interested students can directly apply to .
