Title: Measurement of Magnon Quantum Geometry

Abstract: Quantum geometry describes how a quasiparticle’s wavefunction changes across momentum space, shaping its response to external perturbations. Although quantum geometry underlies many proposed effects in quantum materials, measuring it directly in a solid has been challenging. In this seminar, I will introduce a method to extract magnon quantum geometry from inelastic neutron scattering by relating the measured dynamical structure factor to the momentum-dependent magnon wavefunction.
