Orbital magnetoelectric effect in zigzag nanoribbons of p-band systems
Tarik P. Cysne, Filipe S. M. Guimarães, Luis M. Canonico +2
Profiles of the spin and orbital angular momentum accumulations induced by a longitudinally applied electric field are explored in nanoribbons of -band systems with a honeycomb…
Disentangling orbital and valley Hall effects in bilayers of transition metal dichalcogenides
Tarik P. Cysne, Marcio Costa, Luis M. Canonico +3
It has been recently shown that monolayers of transition metal dichalcogenides (TMDs) in the 2H structural phase exhibit relatively large orbital Hall conductivity plateaus within…
Orbital Hall Insulating Phase in Transition Metal Dichalcogenide Monolayers
Luis M. Canonico, Tarik P. Cysne, Alejandro Molina-Sanchez +2
We show that H-phase transition metal dichalcogenides (TMDs) monolayers such as MoS and WSe, are orbital Hall insulators. They present very large orbital Hall conductivity…
Two-dimensional orbital Hall insulators
Luis M. Canonico, Tarik P. Cysne, Tatiana G. Rappoport +1
The orbital-Hall effect (OHE), similarly to the spin-Hall effect (SHE), refers to the creation of a transverse flow of orbital angular momentum that is induced by a longitudinally…
Spin and Charge Transport of Multi-Orbital Quantum Spin Hall Insulators
Luis M. Canonico, Tatiana G. Rappoport, R. B. Muniz
The fabrication of bismuthene on top of SiC paved the way for substrate engineering of room temperature quantum spin Hall insulators made of group V atoms. We perform large-scale q…
Shubnikov-de Haas oscillations in the anomalous Hall conductivity of Chern insulators
Luis M. Canonico, José H. García, Tatiana G. Rappoport +2
The Haldane model on a honeycomb lattice is a paradigmatic example of a system featuring quantized Hall conductivity in the absence of an external magnetic field, that is, a quantu…
