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:

  • Participating in the ERC project titled ‘FunClocks’ and in other international cooperation projects
  • Working with our team to install and characterize a new ion trap to improve the uncertainty of the system to less than 10‑18
  • 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
  • Developing optical clocks based on HCIs with an uncertainty of 10‑18
  • Presenting the scientific results at international conferences

 

Your profile: 

  • You have successfully completed your university studies in physics (Master’s degree or German Diplom).
  • You are interested in developing and performing high-precision experiments.
  • You are highly committed and capable of working autonomously.
  • You are a strong team player with excellent communication skills.
  • You have a very good command of spoken and written English.
  • A good knowledge of atomic physics, quantum optics, laser cooling, laser spectroscopy, or related fields would be an advantage.
  • You must have the physical ability to work in a laboratory and perform experiments at external sites.

 

We offer:

  • A position at one of the world’s leading research institutions which has an excellent infrastructure
  • Excellent national and international connections
  • 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
  • Research leave abroad via our wide-ranging network
  • Compatibility of work and family life (flexible working hours and part-time schemes)
  • Remuneration in accordance with the collective bargaining agreement for the public service (Tarifvertrag öffentlicher Dienst Bund – TVöD for the federal level)
  • In-house daycare center and canteen
  • Various workplace health and wellness options

 

The post is initially limited to two years; an extension of the contract is possible. You will be employed at our Braunschweig site.

In the research group "Quantum Logic Spectroscopy" we deal with precision spectroscopy of trapped and laser-cooled atomic ions. Therefore, we develop quantum computer-inspired techniques for the coherent manipulation of ions and their spectroscopy for applications such as high-precision optical atomic clocks.

Your tasks:

  • Development of compact optical setups with automated optimisation of operating parameters

  • Integration of the resulting hardware in a transportable Al+ quantum logic clock

  • Participation in the automation of the clock for continuous operation and characterisation of the clock

  • Participation in in-field measurement campaigns outside the laboratory environment for relativistic geodesy

The post is initially limited to three years; an extension of the contract is possible. You will be employed at our
Hannover site in the brand-new HITec lab building. The remuneration will be paid in accordance with up to remuneration group 14 TVöD Bund (100 %).

We offer:

  • An excellent research environment (DQ-mat CRC 1227, Excellence Cluster 2123) with access to PTB's unique infrastructure
  • Practical 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.
  • Possibility to present scientific results at international conferences
  • We encourage research stays abroad with our international collaborators

Your profile:

  • You have obtained an excellent university degree in physics
  • You are interested in developing and realising precision experiments
  • You are highly committed and capable of working both autonomously and together as part of a team, and you are willing to improve your skills
  • You are a team player and have good communication skills
  • Sound knowledge of atomic physics and experience in the field of quantum optics, laser cooling, laser
    spectroscopy or related subjects is advantageous
  • You have the physical ability to work in a laboratory and to perform experiments outside the institute
