TL;DR: An effective model of proximity modified graphene with broken time-reversal symmetry with staggered intrinsic spin-orbit and uniform exchange coupling gives topologically protected pseudohelical states, whose spin is opposite in opposite zigzag edges.

TL;DR: It is found that the magnitude of the interfacial SOT, caused by the reduced symmetry at the interface, is comparably strong as in ferromagnetic metal/non-magnetic metal systems, and suggests that single crystalline Fe/GaAs interfaces may enable efficient electrical magnetization manipulation.

TL;DR: In this paper, the authors investigated topological properties of spin-orbit coupling on realistic substrates and showed that the spin character and robustness of the pseudohelical modes is best exhibited on a finite flake, which shows that the edge states have zero g factor, carry a pure spin current in the cross section of the flake and exhibit spin-flip reflectionless tunneling at the armchair edges.

TL;DR: In this paper, the spin-orbit fields for the relevant valence and conduction bands at the zone center were extracted by fitting the spin splittings resulting from the lack of space inversion symmetry of these bulk crystal structures, to known functional forms.

TL;DR: In this article, the authors performed extensive first-principles calculations for heterostructures composed of monolayer graphene and hexagonal boron nitride (hBN) and employed a symmetry-derived minimal tight-binding model to extract orbital and spin-orbit coupling (SOC) parameters for graphene on hBN, as well as for hBN encapsulated graphene.
