PhD Student in Physics | 26-26-4B Doktorandin / Doktorand (m/w/d) Physik

Job Summary

This doctoral position at the National Metrology Institute of Germany (PTB) focuses on the advanced development of optical clocks using the 173Yb+ isotope. As a PhD candidate, you will work within the 'Optical Clocks with Trapped Ions' group to automate clock operations and investigate stability improvements through multi-ion interrogation and entanglement. Your daily responsibilities include developing protocols for hyperfine transitions, determining systematic frequency shifts, and expanding Python-based experiment control systems using ARTIQ. You will also manage laser setups and conduct comparative measurements to search for physics beyond the Standard Model. This role is highly attractive as it offers a research-focused environment without teaching obligations, access to world-class infrastructure, and a dedicated PhD support program. The position is based in Braunschweig and provides a unique opportunity to present findings at international conferences and publish in leading scientific journals.
