Postdoc Imaging Spin Wave-superconductor Interaction Using Spins in Diamond

The goal of this project is to realize superconducting spin-wave optics and study this at the micro-to-nanoscale using spins in diamond.

Job description

Research in the van der Sar lab:

Our lab studies how interacting charges and spins move through materials. To this end, the lab has developed a technique for imaging spin waves - microscopic waves in magnetic materials - based on magnetic sensing with nitrogen-vacancy (NV) spins in diamond.

Spin waves could enable information technology with new functionalities due to their wave nature, microwave frequencies, strong interactions, and low intrinsic dissipation. A key requirement is to realize efficient spin-wave control. In this project, you will develop superconductor-based control of spin waves while studying the interaction between magnets and superconductors with high spatial resolution and developing new ways to excite, guide, and detect spin waves.

To study the spin waves and the superconductors, you will use a cryogenic, NV imaging system that combines techniques from quantum optics and quantum information processing with device- and microwave engineering

Job requirements

The project revolves around NV centers in diamond, single-spin control, magnetization dynamics, superconductivity, single-photon and atomic-force microscopy, microwave engineering, cryogenic measurements, and electronic characterization. Experience in these fields is highly desirable, though not strictly required. Most importantly, the candidate should be highly motivated to develop state-of-the-art NV microscopy of spin dynamics and supercurrents. A PhD degree in physics and fluency in English are required.
