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…
Quantum Electrodynamics of graphene Landau levels in a deep-subwavelength hyperbolic phonon polariton cavity
Gian Marcello Andolina, Matteo Ceccanti, Bianca Turini +4
The confinement of electromagnetic radiation within extremely small volumes offers an effective means to significantly enhance light-matter interactions, to the extent that zero-po…
Phonon spectra, quantum geometry, and the Goldstone theorem
Guglielmo Pellitteri, Zenan Dai, Haoyu Hu +5
Phonons are essential quasi-particles of all crystals and play a key role in fundamental properties such as thermal transport and superconductivity. In particular, acoustic phonons…
Polariton-induced superconductivity in two-dimensional metals
Riccardo Riolo, Frank H. L. Koppens, Pablo Jarillo-Herrero +3
The electronic properties of two-dimensional (2D) metals are altered by changes in their three-dimensional dielectric environment. In this Letter we propose that superconductivity…
