Subject Area

Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 274200144
This project aims to exploit multi-ion/multi-species systems for precision spectroscopy, optical clocks, and tests for new physics. In DQ-mat we have demonstrated optical clocks using few ion crystals, applying dynamical decoupling and entanglement, and provided the most stringent bounds on LLI. In the future, we will increase the number of ions and ensembles, utilize dynamical decoupling of designed entangled states to improve the statistical and systematic uncertainty well beyond that accessible with single ion clocks. These systems will allow us to further improve tests of LLI and to contribute to searches for dark matter and variation of fundamental constants through clock comparisons with other projects.
