Covariant Conservation Laws and the Spin Hall Effect in Dirac-Rashba Systems.
We present a theoretical analysis of two-dimensional Dirac-Rashba systems in the presence of disorder and external perturbations. We unveil a set of exact symmetry relations (Ward identities) that impose strong constraints on the spin dynamics of Dirac fermions subject to proximity-induced interactions.
ReadOptimal Charge-to-Spin Conversion in Graphene on Transition-Metal Dichalcogenides
When graphene is placed on a monolayer of semiconducting transition metal dichalcogenide (TMD) its band structure develops rich spin textures due to proximity spin-orbital effects with interfacial breaking of inversion symmetry.
