The impact of Rashba spin-orbit coupling in charge-ordered systems
Rodrigo A. Fontenele, Sebastião dos Anjos Sousa-Júnior, Tarik P. Cysne +1
We study the impact of the Rashba spin-orbit coupling (RSOC) on the stability of charge-density wave (CDW) in systems with large electron-phonon coupling (EPC). Here, the EPC is co…
Probing topological phase transitions via quantum reflection in the graphene family materials
P. P. Abrantes, Tarik P. Cysne, D. Szilard +3
We theoretically investigate the quantum reflection of different atoms by two-dimensional (2D) materials of the graphene family (silicene, germanene, and stanene), subjected to an…
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…
