at the Department of Physics. Closing date: (March 19, 2021). Extended to May 15, 2021. 

The Department of Physics is one of the biggest departments within the Faculty of Science and supports a broad range of basic research in experimental and theoretical physics. It has about 250 employees of which 95 are PhD students. Many have been internationally recruited. The Department is part of the AlbaNova University Center, which apart from the Department of Physics houses the Department of Astronomy, the Physics Departments at the Royal Institute of Technology (KTH), and the Nordic Institute for Theoretical Physics (Nordita). 

The Department of Physics and Stockholm University is affiliated to Stockholm Dual Career Network (SDCN) that supports expat partners with professional events, career-related advice and by building a social network in their new hometown.

Project description
The Oskar Klein Centre and the Department of Physics at Stockholm University invites applications for a Postdoctoral fellow focusing on the design and testing of lightweight metamaterial candidates for broadband millimeter-wavelength absorbers to be used by the LiteBIRD satellite. 

The successful candidates will be part of the Oskar Klein Centre for Cosmoparticle Physics ( in Stockholm, a rich scientific environment that comprises more than a hundred researchers working in both theory and experiment in the fields of astronomy, astrophysics and particle physics at both Stockholm University and the Royal Institute for Technology.

The OKC hosts a vibrant research program on dark matter, dark energy, transient and multimessenger astrophysics, structure formation, and related particle physics questions. Postdoctoral associates are also welcome to participate in Scientific Programs at Nordita, the Nordic Institute for Theoretical Physics, which bring together groups of leading experts to work on specific topics for extended periods. Stockholm, which spreads across a beautiful archipelago located in the Baltic Sea, offers easy access to a diverse set of nature activities and cultural experiences.

Main responsibilities
We are advertising a 2-year postdoc employment, funded by the Swedish Space Agency, to work on the development and testing of mm-wavelength absorbers for the LiteBIRD satellite. The project involves further development of existing technologies while optimizing for broadband and wide-angle absorption, low mass, and cryogenic robustness.

The custom materials will be tested against well-known absorber solutions under a range of conditions mimicking those that will likely be seen in a 4th-generation CMB satellite, LiteBIRD led by JAXA, observing at frequencies covering 40-400 GHz. We anticipate that progress on this work effort will be discussed during weekly meetings within the LiteBIRD Collaboration.

Qualification requirements
Postdoctoral positions are appointed primarily for purposes of research. Applicants are expected to hold a Swedish doctoral degree or an equivalent degree from another country.

Assessment criteria
The degree should have been completed no more than three years before the deadline for applications. An older degree may be acceptable under special circumstances, which may involve sick leave, parental leave, clinical attachment, elected positions in trade unions, or similar.

In the appointment process, special attention will be given to proven experience in mm-wavelength instrumentation, particularly experience with quasi-optical testing for experiments observing the cosmic microwave background. Similarly, any experience with testing of mm-wavelength telecommunication systems is beneficial.

We are looking for driven candidates with strong ability to work both individually and in groups. Good command of the English language is essential.

Terms of employment
The position involves full-time employment for a maximum of two years, with the possibility of extension under special circumstances. The proposed start date is September 1, 2021 (negotiable).

Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
