Junior Research Group Leader: Novel Frequency References

We seek a talented physicist who is interested in establishing their long-term career in science at PTB, with many collaborations within the QuantumFrontiers consortium and with international partners. Application Deadline: October 14th, 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.

Junior Research Group Leader 

for research in the field of

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.

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.
