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…
Roadmap for Photonics with 2D Materials
F. Javier GarcÃa de Abajo, D. N. Basov, Frank H. L. Koppens +145
Triggered by the development of exfoliation and the identification of a wide range of extraordinary physical properties in self-standing films consisting of one or few atomic layer…
Optical properties, plasmons, and orbital Skyrme textures in twisted TMDs
Lorenzo Cavicchi, Koen J. A. Reijnders, Mikhail I. Katsnelson +1
In the long-wavelength limit, Bloch-band Berry curvature has no effect on the bulk plasmons of a two-dimensional electron system. In this Letter we show instead that bulk plasmons…
