Magnetic fluctuations driven by quantum geometry
Makoto Shimizu, Chang-guen Oh, Youichi Yanase
Using quantum distance, magnetic susceptibility in the non-interacting limit can be rigorously split into two contributions: one arising solely from band dispersion, while the othe…

Color and Transparency from Quantum Geometry
Chang-geun Oh, Sun-Woo Kim
The optical properties of solids are governed not only by their energy band dispersions but also by the quantum geometry of Bloch states. While the role of energy bands in determin…
