Research Fellow (Ultra-stable Cavities)

Research Fellow (Ultra-stable Cavities)


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 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 further advance clock performance and develop local expertise in optical clocks, we now looking to establish in-house capabilities in the design and implementation of ultra-stable optical resonators.

 

Job Description:


We currently have a project aimed at improving clock interrogation through improved laser stabilization. In this project, the candidate will have a leadership role in the design and implementation of an ultra-stable optical cavity. Design work will involve extensive simulations of mechanical and thermal responses of environmental isolation enclosures. It is expected that the candidate will work closely with the laboratory team to better characterize existing cavity setups and to experimentally demonstrate improved clock performance in a multi-ion clock system.

 

 

Requirements:

 

  • PhD in experimental Physics/Engineering ideally with expertise in atomic physics and/or atomic clocks.
  • Working experience with COMSOL simulation software and 3D CAD programs such as SolidWorks or Autodesk Inventor.
  • Practical experience with high performance lasers.
  • Fluency in written and spoken English.

 


The remuneration is competitive and depends on the expertise and skill set.
