Gyrotropic Fingerprints of Magnetic Topological Insulator-Unconventional Magnet Interfaces
This research uses Zeeman quantum geometry to characterize unconventional magnetic insulators at interfaces with topological insulators. By analyzing intrinsic gyrotropic transport responses, the study shows that different magnetic orders (p-, d-, f-, g-, i-wave) leave unique angular fingerprints on the displacement current, allowing for high-fidelity identification of these complex phases.
