Postdoc Positions

Cryogenic HCI trap

Open Positions

Highly charged ions (HCIs) are ubiquitous in the observable universe and have many advantageous properties for fundamental physics tests and use as next-generation optical clocks. Building on our recent breakthrough in the clock-like laser spectroscopy of highly charged ions with a precision jump of nine orders of magnitude, the following tasks will be pursued:

  • Working with our team to install and characterize an improved ion trap based on precision-machined wafer technology to further improve the performance of the system

  • Developing quantum logic search techniques to enable the rapid localization and identification of narrow optical transitions in HCIs

  • Performing optical frequency measurements at the technological limit and analyzing isotopic shift data with respect to the exclusion of 5th forces

 

The post is initially limited to three years; an extension of the contract is possible. You will be employed at our Braunschweig site. The remuneration will be paid in accordance with remuneration group 13 TVöD Bund.

 

We offer:

  • An excellent research environment with access to PTB’s unique infrastructure

  • Hands-on training in modern experimental techniques in laser and quantum physics and active participation in the development of experiments at the forefront of quantum physics research

  • The opportunity to present scientific results at international conferences

  • We support research trips abroad in cooperation with our international partners

Your profile:

  • You have completed your university studies (diploma/master’s) in physics with a very good degree; a doctorate would be an advantage

  • You are interested in developing and performing high-precision experiments

  • You have a high level of commitment, you work well both independently and in a team, and you have a willingness to learn

  • You are a strong team player with excellent communication skills

  • You have a very good command of both spoken and written German and English

  • Having a good knowledge of atomic physics, quantum optics, laser cooling, laser spectroscopy, or related fields is an advantage

  • The physical ability to work in a laboratory and to perform experiments at external sites is required
