Position: We are opening a postdoctoral research position to perform spin-wave spectroscopy on a home-built NV-center microscope. The scientific goal is to exploit the exquisite sensitivity of the instrument to map the spatio-temporal profile of otherwise hidden azimuthal modes. Our long-term objective is to develop a high-performance orbital-angular-momentum transducer between photons, magnons, and phonons, using a micron-sized, cylindrically shaped magnetic garnet crystal.
Three patents have been filed on the original design of the microscope and the developped setup has already demonstrated unsurpassed spectral resolution. This project is particularly well suited to tech-savvy applicants who enjoy a hands-on, “nuts and bolts” approach to experimental physics. The position involves the use of a broad range of experimental skills spanning optics, microwave technology, mechanics, analog electronics, and computer interfacing in Python.

ProfileThe successful candidate will hold a PhD in Solid State Physics, Quantum Physics, or Applied Physics. Candidates with a strong instrumentation background and a demonstrated ability to design, build, and troubleshoot experimental setups from the ground up are particularly encouraged to apply. Experience in one or more of the following areas is desirable: microwave engineering, confocal microscopy, magnetic resonance spectroscopy, scanning probe microscopy, and scientific programming in Python. Prior experience with hardware electronics such as Raspberry Pi, Arduino, or FPGA will be considered an asset.
How to apply: The Applicants should submit a CV with publications, including research interests and motivation (2 pages maximum), up to 2 recommendation letters (from academic supervisors or collaborators), and academic transcripts (PhD certificate and reports).
Application materials can be submitted in English or French via email to Dr. Olivier KLEIN with the subject line clearly marked as “Postdoctoral Application – Insulatronics”. The selection process will involve a deadline for submissions (15/10/2027), after which shortlisted candidates will be invited for an online interview to discuss their technical expertise and alignment with the project. The successful candidate is expected to start a CEA contract position by 01/01/2027, with some flexibility.
