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…
Roadmap for Photonics with 2D Materials
F. Javier García 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…
Recognizing molecular chirality via twisted 2D materials
Lorenzo Cavicchi, Mayra Peralta, Álvaro Moreno +6
Chirality pervades natural processes from the atomic to the cosmic scales, crucially impacting molecular chemistry and pharmaceutics. Traditional chirality sensing methods face cha…
Twisted bilayer graphene for enantiomeric sensing of chiral molecules
Álvaro Moreno, Lorenzo Cavicchi, Xia Wang +8
Selective sensing of chiral molecules is a key aspect in fields spanning biology, chemistry, and pharmacology. However, conventional optical methods, such as circular dichroism (CD…
Giant chirality-induced spin polarization in twisted transition metal dichalcogenides
Guido Menichetti, Lorenzo Cavicchi, Leonardo Lucchesi +6
Chirality-induced spin selectivity (CISS) is an effect that has recently attracted a great deal of attention in chiral chemistry and that remains to be understood. In the CISS effe…
Theory of intrinsic acoustic plasmons in twisted bilayer graphene
Lorenzo Cavicchi, Iacopo Torre, Pablo Jarillo-Herrero +2
We present a theoretical study of the intrinsic plasmonic properties of twisted bilayer graphene (TBG) as a function of the twist angle (and other microscopic parameters such a…
