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…
Formal Integration of Electron Scattering Processes via Separation of Dynamical and Geometric Contributions
Lorenzo Bagnasacco, Fabio Taddei, Vittorio Giovannetti
By decoupling the geometric from the dynamical contributions in the scattering processes, we develop a method to compute the scattering matrix of electrons in a one-dimensional coh…
Heat-charge separation in a hybrid superconducting quantum Hall setup
Carlo Panu, Fabio Taddei, Marco Polini +1
Separating heat from charge in a material is an extremely challenging task since they are transported by the very same carriers, i.e. electrons or holes. In this Letter we show tha…
