Venue: Peyresq, France
Date: 26 July to 2 August 2026
Introduction:
In condensed matter systems with flat bands, the kinetic energy is suppressed and correlation effects dominate. But perhaps more interestingly, when the electronic interaction is projected onto the flat band, the shape of the wave function—the quantum geometry—crucially affects the fate of the resulting electronic state. In particular the form factor of the electron-electron interaction depends on how the wave function overlaps at different momenta. This form factor is directly related to the quantum metric and Berry curvature. This notion greatly impacts modern aspects of quantum many-body physics and quantum material research. This includes the novel phases discovered in magic angle twisted bilayer graphene, fractional quantum anomalous Hall (FQAH) insulators in Moiré materials, and the relation between these FQAH states and Landau level, as well as the projection of the latter in the realm of the fuzzy sphere approach to quantum criticality etc.
The aim of this workshop is to bring together a small group of researchers interested in this broad subject, including field theorists, computational and experimental physicists. The remote location in the charming village of Peyresq is ideal to promote discussions across generations and fields of specializations.
