Quantum Metrology Group
Our group has developed an optical atomic clock based on Lu+. Lutetium is a unique clock candidate in that it supports three clock transitions within the one atom enabling rigorous consistency checks on clock performance. We have shown that two of these transitions have very low systematic shifts making them competitive with the best systems in the world. In 2019 we demonstrated the feasibility of operating the clock with multiple ions which will enable improvements in measurement precision. More recently we demonstrated agreement between two clocks at the level of 10-18, which was limited by the measurement statistics and not systematic uncertainty. To provide further advancement in clock performance we are now investigating more practical approaches to multi-ion operation.
Practical clock operation with a small array of ions requires an elimination of background collisions which is best achieved in a cryogenic environment. In this project the candidate will be responsible for the design and implementation of a cryogenic ion-trap apparatus. Candidate will work closely with members of the team to determine key design criteria and with external companies in the design of a suitable cryostat system. Candidate will also be expected to have a leadership role in experiments to characterize the system and demonstrate clock operation.
- PhD in experimental Physics/Engineering ideally with expertise in ion-traps and atomic physics.
- Practical experience with cryogenic systems.
- Experience with 3D-Cad software such as SolidWorks or Autodesk Inventor.
- Fluency in written and spoken English.
The remuneration is competitive and depends on the expertise and skill set.
