Titre Quantum Hall effect and vector bundles over moduli spaces of curves and Jacobians
Horaire16:00 à 17:00
RésumeVector bundles of so-called Laughlin states were introduced by physicists to study the fractional quantum Hall effect. Their Chern classes are related to measurable physical quantities. We will explain how they are related to the vector bundle of theta-functions over the moduli space and to certain vector bundles over the Jacobians. We perform the first steps in the computation of their Chern classes. Work in progress with Semyon Klevtsov.
