- Orbital magnetism and flat bands in magnetic field
- Time: 10:00 am - 6:00 pm
- Place: 5310 Chamberlin Hall
- Speaker: Oskar Vafek , UMN-FTPI
- Abstract: I will discuss recent theoretical progress in understanding the role played by the electron-electron interactions in orbital magnetism, and highlight results obtained for the flat bands of the magic angle twisted bilayer graphene, as well as for some twisted transition metal dichalcogenides. I will also discuss the effect of the external out-of-plane magnetic field on the correlated ground states and their excitations, and compare the ensuing Landau level degeneracies with the experimental observations.
- Host: Alex Levchenko
