Simulating the Haldane model in ultra-clean GaAs heterostructures
Francesco Cioni, Lorenzo Cavicchi, Fabio Taddei +1
The Haldane model represents the minimal lattice-based realization of a Chern insulator, exhibiting a quantized Hall conductance in the absence of Landau levels. Despite its concep…

Persistent currents, whirlpools, and local Chern markers in twisted TMD Chern insulators
Francesco Cioni, Lorenzo Cavicchi, Nazzareno Africani +4
Recent materials advances have made it possible to fabricate twisted transition metal dichalcogenide homobilayers. These systems have been shown to host integer and fractional Cher…
