This project, carried out at the Condensed Matter Theory group of JYU, will theoretically investigate the recently discovered supercurrent diode effect (SDE) in new quantum materials. This effect shows up via a non-reciprocal current flow when both time-reversal and inversion symmetries are broken in the superconductor: supercurrent can flow in one direction, whereas only a regular dissipative Ohmic current can flow in the other. SDE is a useful new tool to probe microscopic properties of superconductors by simple electrical measurements, and it has a potential to provide a building block for the new generation of cryogenic electronics. SDE is currently a topic at the forefront of research in condensed matter physics. It is observed in a handful of systems, but many of its aspects are currently poorly understood. Our results will contribute to filling this knowledge gap, and will be of direct relevance for realization of new quantum technologies based on SDE.
