Robustness of real-space topology in moiré systems
Kryštof Kolář, Kang Yang, Felix von Oppen +1
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
Kryštof Kolář, 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…

Robust spectral pairing in the random-field Floquet quantum Ising model
Harald Schmid, Alexander-Georg Penner, Kang Yang +2
Motivated by an experiment on a superconducting quantum processor [Mi et al., Science 378, 785 (2022)], we study level pairings in the many-body spectrum of the random-field Floque…
