Direct observation of flat bands in near-magic-angle twisted bilayer CVD graphene
Gianluigi Baiardi, Alex Boschi, Giulia Piccinini +13
Advances in chemical vapor deposition (CVD) growth have driven graphene crystal quality to unprecedented levels, yet it is still unknown whether this route can realize the fragile…
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…
Theory of nonlinear spin transport in chiral conductors
Lorenzo Cavicchi, Marco Polini
The chirality-induced spin selectivity (CISS) effect, discovered by Naaman and collaborators in 1999, describes the emergence of a finite spin polarization in response to current f…
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…
