Dispersion of Anyon Bloch Bands
Kishore Iyer, Andreas Feuerpfeil, Valentin Crépel +2
Fractional Chern insulators (FCIs) are zero magnetic field analogs of fractional quantum Hall states. While the electrons forming an FCI are not subject to an external magnetic fie…
Robustness of real-space topology in moiré systems
KryÅ¡tof KoláÅ, Kryštof Kolář, Kang Yang +2
The appearance of fractional Chern insulators in moiré systems can be rationalized by the presence of a fictitious magnetic field associated with the spatial texture of layer-resol…
Hofstadter spectrum of Chern bands in twisted transition metal dichalcogenides
KryÅ¡tof KoláÅ, Kang Yang, Felix von Oppen +1
We study the topological bands in twisted bilayer transition metal dichalcogenides in an external magnetic field. We first focus on a paradigmatic model of WSe, which can be de…
Layer skyrmions for ideal Chern bands and twisted bilayer graphene
Daniele Guerci, Jie Wang, Christophe Mora
Ideal Chern bands exhibit a Landau level correspondence: they factorize as a lowest Landau levels and a spinor wavefunction that spans the layer index. We demonstrate that, i…
Helical trilayer graphene in magnetic field: Chern mosaic and higher Chern number ideal flat bands
Anushree Datta, Daniele Guerci, Mark O. Goerbig +1
Helical trilayer graphene (hTG) exhibits a supermoiré pattern with large domains centered around stacking points ABA and BAB, where two well-separated low-energy bands appear with…
