Generalized Landau levels and harmonic band theory
8 octobre 2026 - 11:00Salle de conférences IRMA
We introduce and study harmonic bands through the geometry of holomorphic curves and their associated Frenet–Serret frames. Starting from an ideal band, we construct a family of bands—which we call generalized Landau levels—whose associated maps to projective space are harmonic, and express their quantum metric and Berry curvature in terms of consecutive osculating curves. We then show explicitly how ordinary Landau levels fit into this construction. The lowest Landau level defines a holomorphic curve in projective Hilbert space, and its Frenet–Serret frame represents all higher Landau levels. Thus ordinary Landau levels are generalized Landau levels and provide the canonical examples of harmonic bands. -
