Topological Superconductors and Kagome Magnets

Recently, Prof. Ziqiang Wang and Dr. Kun Jiang, and collaborators from Princeton University, University of Illinois at Urbana-Champaign, Institute of Physics, and Peking University reported their research findings in the area of topological quantum materials. These include the discovery of chiral topological superconductivity in heavy fermion superconductor UTe₂ published in Nature; incipient topological superconductor and Majorana zero modes at both ends of atomic line defects in monolayer Fe(Te,Se) superconducting films in Nature Physics; and Majorana zero modes at magnetic Fe adatoms in Science Advances, supporting their theory of the quantum anomalous vortex. They also reported that the Kagome lattice TbMn₆Sn₆ is a topological Chern magnet in Nature, exhibiting a Chern gap and topological edge states; the discovery of magnetic spin-orbit polarons at atomic S-vacancies in Kagome magnetic Weyl semimetal Co₃Sn₂S₂ in Nature Communications; and spin-orbit coupled magnetic resonances in Co₃Sn₂S₂ in Nature Communications.
