Short description of the group/project/topic of research

What if a single Josephson Junction could host a topological phase, a long-range spin-triplet current, and a resonant magnon-fluxon interaction — all in one device?

At the NISE department of the Max Planck Institute of Microstructure Physics, we’re not just studying Josephson junctions — we’re engineering quantum reality. We’re seeking a bold, hands-on experimentalist to join our team in pioneering quantum-coherent hybrid devices that merge superconductivity, magnetism, and topology — pushing the boundaries of what’s possible in quantum materials.

You’ll lead the design and characterization of next-generation Josephson junctions — not just measuring transport, but engineering quantum states. Your work will probe the emergence of long range spin-triplet supercurrents, coherent magnon-fluxon coupling and topological superconductivity — all in real devices at the quantum frontier.

Additional information

Your Mission:

  • Engineer Josephson junctions with ferromagnetic interlayers, non-collinear magnetic structures, and 2D van der Waals heterostructures to generate and control long-range spin-triplet supercurrents — and detect their exotic signatures.
  • Probe the AC Josephson effect, non-sinusoidal current-phase relations, and anharmonic junction dynamics using microwave techniques — revealing hidden phase coherence, topological transitions, and quantum fluctuations.
  • Explore resonant coupling between spin waves (magnons) and Josephson vortices (fluxons) — laying the foundation for coherent information transfer in hybrid magnonic-superconducting circuits.
  • Build and test devices that bridge quantum coherent transport, superconducting spintronics, and topological states — turning fundamental physics into real-world quantum technologies.

You Are:

  • A PhD physicist or materials scientist with experience in cryogenic quantum transport, nanofabrication, and microwave measurements.
  • Driven by the thrill of discovery — not just data, but first-of-a-kind observations.
  • Comfortable in the cleanroom, the cryostat, and the lab notebook — and ready to build the quantum devices of tomorrow.
  • A creative problem-solver who thrives in an international, interdisciplinary team — and who publishes with impact.

Join us!
This isn’t just a postdoc. It’s your chance to help build the next generation of quantum technologies.
