Doctoral Candidate in Physics (Optical Clocks) | Doktorandin / Doktorand (m/w/d) Physik (25-226-4B)

Job Summary

This doctoral position at the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig focuses on cutting-edge research in precision metrology, specifically advancing optical clock technology using the 173Yb+ isotope. The candidate will be responsible for automating clock operations, investigating stability improvements through multi-ion interrogation and entanglement, and developing protocols for using hyperfine transitions. Key tasks include determining systematic frequency shifts, expanding Python-based experimental control systems using ARTIQ, and enhancing existing laser setups. The role involves performing comparison measurements with other optical clocks to verify uncertainties and search for physics beyond the Standard Model. This is an attractive opportunity for a highly committed experimental physicist to focus entirely on their PhD research within an internationally renowned team and contribute to world-leading measurement standards.
