Junior Research Group Leader for the research group focusing on Novel Frequency References (19-098-4)Monday, 14. October 2019

The Physikalisch-Technische Bundesanstalt (PTB) is the National Metrology Institute of the Federal Republic of Germany with scientific and technical service tasks. It furthers progress and reliability in metrology for society, the economy and science.


Department 4.3 “Quantum Optics and Unit of Length” of Division 4 is looking for a


Junior Research Group Leader
for the research group focusing on
Novel Frequency References

to join us as soon as possible. This position is on offer within the framework of the QuantumFrontiers Cluster of Excellence, a consortium with Leibniz University Hannover and TU Braunschweig.


The position is initially limited to three years. You will be employed at our Braunschweig site.

After successful evaluations, the position can be extended for three more years and afterwards changed into a permanent staff position at PTB.

The remuneration will be paid in accordance with remuneration group 14 TVöD Bund.


Your tasks:

At PTB, we currently achieve lasers with the best frequency stabilities worldwide. We employ these ultra-stable frequency references with high phase coherence in our optical clocks and in tests of fundamental physics. In anticipation of the expanding applications of ultra-stable frequency references, particularly for fundamental metrology and for portable devices, we seek an outstanding candidate to head an experimental research group at PTB, which will meet the diverse, long-term needs of this field.

Under the mentoring of a PTB scientist, we expect close collaboration with fellow PTB scientists and partners within the QuantumFrontiers Cluster of Excellence on current research pursuits; these include research activities on ultra-stable optical cavities, low-thermal-noise mirrors and improved optical clock performance.

PTB, TU Braunschweig and Leibniz University Hannover offer an exciting collaborative research environment at an internationally competitive level as well as laboratories with state-of-the-art facilities.

To establish your own personal research activities in this field, the position includes core support from the Cluster of Excellence for funding a PhD student as well as for equipment for your own research activities in this field such as,

  • optical cavities at ultralow temperatures
  • active atomic light sources
  • solid-state-based narrow linewidth frequency references and
  • micro-optical systems.


Your profile:

  • You have completed your university studies (German Diplom or Master's) in physics and have obtained a very good doctoral degree.
  • You have published other relevant papers.
  • You have international research experience.
  • You have relevant postdoc experience.
  • You have performed research that is closely related to the work in the Cluster of Excellence as well as to PTB.
  • You have a very good command of English. A very good command of German would be desirable.
  • You have excellent communication skills and are a team player.
  • Your style of work is self-reliant, independent and well structured.
  • You are highly committed and empathetic.
  • You are physically able to work in a laboratory.
  • You are willing to travel within Germany as well as abroad within the scope of your assignments.
