For our location in Zeuthen we are seeking:

Postdoc for a networked atomic clock experiment for ultralight dark matter

Limited: 3 years | Starting date: 01.07.2023 | ID: APPO003/2023 | Deadline: 31.05.2023 | Full-time/Part-time

DESY, with more than 2900 employees at its two locations in Hamburg and Zeuthen, is one of the world's leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.

The Zeuthen location of DESY has a strong focus on astroparticle and particle physics (gamma-ray and neutrino astronomy, and collider particle physics). The experimental groups are accompanied by a strong theory group. DESY Zeuthen is responsible for developing and delivering detectors for astroparticle and particle physics experiments, and is actively engaged in R&D for future applications.

With the Centre for Quantum Technology and Applications (CQTA), DESY Zeuthen is taking a leading role in applying quantum technology to challenges in particle and astroparticle physics. A new search for the effects of ultralight dark matter is being constructed, using ultra-sensitive optical atomic clocks as the sensing element. The post holder will contribute to this search, driving the development of a test setup for networked clock comparison and frequency stabilisation. The post holder will also help to develop the procedures to collect and analyse the frequency comparisons, forming the basis of fundamental physics searches for (e.g.) ultralight dark matter.

About your role:

  • Active role in networked clock comparisons for dark matter and fundamental physics measurements;
  • Develop a test network including frequency comb and optical fibres;
  • Participate in the collaboration between DESY, HU, Heidelberg, and U. Birmingham;
  • Analyze experimental atomic clock data and participate in the interpretation of results.

About you:

  • PhD in experimental physics or equivalent qualification;
  • Experience with lasers and high frequencies (eg radio) and in one of the relevant physics fields (eg particle, atomic/nuclear physics, quantum optics);
  • Very good command of English is required and knowledge of German is of advantage;
  • Willingness to travel and participate in working meetings, conferences, and field work abroad;
  • Strong motivation, very good organizational skills, resilience; ability to work in teams and excellent communication skills.

Good reasons to join:

Look forward to a unique working environment on our international research campus. We attach particular importance to appreciative cooperation and the well-being of our DESY employees. Gender equality is an important aspect for us. To support work life balance we offer flexible working hours, variable part-time, job-sharing models and participation in mobile work. You will benefit from our family-friendly and collegial atmosphere, our established health management and occupational pension provision. As a public funded employer, we offer you a secure workplace and facilitate your individual career with our comprehensive training and development opportunities. Remuneration is according to the regulations of the TV-AVH. DESY offers its employees a financial supplement for a job ticket at both locations.

DESY profile imageBecome a part of DESY, one of the world’s leading accelerator centres. Researchers use the large-scale facilities at DESY to explore the microcosm in all its variety – from the interactions of tiny elementary particles and the behaviour of new types of nanomaterials, to biomolecular processes that are essential to life.

Why work for us
DESY is not only an employer for 2500 people from more than 65 nations, but also a magnet for more than 3000 guest researchers each year from all over the world using our unique research tools. Committed young researchers find an exciting interdisciplinary setting at DESY. We strive to achieve a balanced relationship between our work at DESY and our private lives, and we promote equal opportunity and a healthy balance between professional and family life.

Training and development
We offer young scientists an international and interdisciplinary setting for ambitious scientific projects, and we provide the appropriate training and working environment for a variety of technical and administrative professions. DESY offers a large number of internal training programmes for all career stages as well as individual talent management courses and mentoring programmes, and therefore supports the career path of every single person in our institute.

Graduate schemes
DESY covers the whole educational lifecycle of a scientist – from internships, summer-school programmes for undergraduates, bachelor and Master’s theses, graduate schools, all the way to specific fellowship programmes, young investigator groups and professorship programmes.

What we are looking for
In order to maintain our top-level position and to achieve our future scientific goals, the highest attribute that we are looking for is passion. This means that we are not only focusing on just the very best talents, but the ones combining knowledge, ambition, curiosity and dedication towards science and its surrounding areas in one personality.
