Abstract: Quantum geometry (QG) is a mathematical framework defined in Hilbert space that characterizes the “distance” between quantum states. Recently, the notion of QG has been used by the Solid-state Physics community as a novel label besides symmetry and topology to characterize quantum materials. In this talk, I will exploit QG as a useful interface that links macroscopic observables to microscopics in unconventional superconductors. I will propose two novel experimental signatures that probe (1) Rashba-induced topological superconductors, and (2) superconductivity driven by multiple Van Hove singularities, respectively.
