We evidence the possibility for coherent electrical manipulation of the spin orientation of topologically protected edge states in a low-symmetry quantum spin Hall insulator. By using a combination of ab initio simulations, symmetry-based modeling, and large-scale calculations of the spin Hall conductivity, it is shown that small electric fields can efficiently vary the spin textures of edge currents in monolayer 1T'-WTe2 by up to a 90-degree spin rotation, without jeopardizing their topological character.

The spin Hall effect (SHE) provides an efficient tool for the production of pure spin currents, essentially for the next generation of spintronics devices. Giant SHE has been reported in Cu doped with 0. [...]

Spin hall effect and origins of nonlocal Resistance in adatom-decorated graphene / Dinh, Van Tuan (Institut Català de Nanociència i Nanotecnologia) ; Marmolejo Tejada, J. M. (University of Delaware. Department of Physics and Astronomy) ; Waintal, Xavier (Université Grenoble Alpes) ; Nikolić, B. K. (University of Delaware. Department of Physics and Astronomy) ; Valenzuela, Sergio O. (Institut Català de Nanociència i Nanotecnologia) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia)
Recent experiments reporting an unexpectedly large spin Hall effect (SHE) in graphene decorated with adatoms have raised a fierce controversy. We apply numerically exact Kubo and Landauer-Büttiker formulas to realistic models of gold-decorated disordered graphene (including adatom clustering) to obtain the spin Hall conductivity and spin Hall angle, as well as the nonlocal resistance as a quantity accessible to experiments. [...]

Bidirectional resonant tunneling spin pump / Ting, David Z. -Y. (California Institute of Technology. Jet Propulsion Laboratory) ; Cartoixà Soler, Xavier (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; American Physical Society
We propose a mechanism for achieving bidirectional spin pumping in conventional nonmagnetic semiconductorresonant tunnelingheterostructures under zero magnetic field. The device is designed specifically to take advantage of the special spin configuration described by the Rashba effect in asymmetric quantum wells. [...]
