Job description

Postdoctoral Fellowship in Experimental Quantum Matter

The Quantum Matter Lab at the Niels Bohr Institute, University of Copenhagen, invites applicants for a postdoctoral fellowship to investigate topologically protected synthetic matter in 1D and 2D arrays of semiconductor-superconductor Josephson junctions formed in a variety of lattices. The project aims to explore novel states and dynamics of emergent quantum states, including topological matter and flat bands.

The expected start date is no later than November 15, 2026.

The project

The work is at the border of quantum simulation and quantum matter, and takes advantage of novel epitaxial hybrid materials. Candidates should have a PhD in condensed matter experimental physics, mesoscopic electron transport, or experimental solid-state quantum information science. The project combines nanofabrication, low-temperature measurements using a cryofree dilution refrigerator, low-noise and high frequency electrical measurement techniques, data analysis, and close collaboration with theoretical physicists. Scientific writing and communication will be in English. Inquiries about the position can be made to Associate Professor Saulius Vaitiekėnas ([e-mail]).

Description of the scientific environment

The Quantum Matter Lab at the Niels Bohr Institute is a research group focused on experimental solid-state physics, quantum nanoelectronics, and condensed matter device physics. The group provides a vibrant scientific environment for cutting-edge experimental research, with close interactions with theorists and potential collaborations with industry. Our group is part of Condensed Matter Physics at the Niels Bohr Institute, Faculty of Science, University of Copenhagen. We are based in Copenhagen and offer creative, stimulating working conditions within a dynamic, international research environment. The University and the group wish our staff to reflect the diversity of society and thus welcome applications from all qualified candidates.

Terms of employment

The average weekly working hours are 37 hours per week. The position is a fixed-term position limited to a period of 2 years, with a possibility of extending the contract further. Salary, pension and other conditions of employment are set in accordance with the Agreement between the Ministry of Taxation and AC (Danish Confederation of Professional Associations) or other relevant organisation. Currently, the monthly salary starts at 35,000 DKK/approx. 4,700 EUR (August 2026 level). Depending on qualifications, a supplement may be negotiated. The employer will pay an additional 18.07 % to your pension fund. Foreign and Danish applicants may be eligible for tax reductions, if they hold a PhD degree and have not lived in Denmark the last 10 years. The position is covered by the Job Structure for Academic Staff at Universities 2025.

The deadline for application is 20 September 2026, 23:59 GMT +2. After the expiry of the deadline for applications, the authorized recruitment manager selects applicants for assessment on the advice of the Interview Committee.

As an equal opportunity employer, the University of Copenhagen invites applications from all qualified candidates, regardless of gender, age, religion, or ethnic origin.

Part of the InternationalAllianceof Research Universities (IARU), and among Europe’s top-ranking universities, the University of Copenhagen promotes research and teaching of the highest international standard. Rich in tradition and modern in outlook, the University gives students and staff the opportunity to cultivate their talent in an ambitious and informal environment. An effective organisation – with good working conditions and a collaborative work culture – creates the ideal framework for a successful academic career.
