Identifying Topological Superconductors from Fermi Surface Information

An international research group including Seishiro Ono, Special Postdoctoral Researcher, Division of Fundamental Mathematical Science, iTHEMS (at the time of the research; currently Visiting Scientist, Division of Global Collaborations and Research Talent Development), has established a theoretical formula that determines the topological properties of superconductors from information on the “Fermi surface,” which describes the electronic states responsible for electrical conduction and superconductivity.

These research results are expected to provide a foundation for efficiently searching for topological superconductors among a vast number of materials, thereby accelerating both theoretical predictions and experimental exploration of candidate materials.
