We study the effects of spin orbit interactions on the low energy electronic structure of a single plane of graphene. We find that in an experimentally accessible low temperature regime the symmetry allowed spin orbit potential converts graphene from an ideal two-dimensional semimetallic state to a quantum spin Hall insulator. This novel electronic state of matter is gapped in the bulk and supports the transport of spin and charge in gapless edge states that propagate at the sample boundaries… Expand

Spin-filtered edge states in graphene
Abstract Spin–orbit coupling changes graphene, in principle, into a two-dimensional topological insulator, also known as quantum spin Hall insulator. One of the expected consequences is the existenceExpand
Rashba-induced spin scattering at graphene edges
We investigate theoretically the behavior of electron spin states near graphene edges at low temperature in the presence of an external electric field. The graphene Hamiltonian is solved directly inExpand
Charge and spin Hall effect in spin chiral ferromagnetic graphene
We predict a specific type of charge Hall effect in undoped ferromagnetic graphene that is generated by the spin Hall mechanism in the absence of an external magnetic field. The essential feature isExpand
Charge and spin Hall conductivity in metallic graphene.
It is predicted that large spin Hall conductivities will be observable in graphene even when the spin-orbit gap does not survive disorder. Expand
The effect of spin-orbit interaction on optical conductivity in graphene.
Key findings are: level splitting at various crystal symmetry points caused by true spin as well as pseudospin of the electrons gives rise to a resonant current response, and under heavy doping, the spin-orbit interaction leads to a re-entrance of finite conductivity at very low frequency. Expand
Charge and spin transport at the quantum Hall edge of graphene
Abstract Landau level bending near the edge of graphene, described using a 2d Dirac equation, provides a microscopic framework for understanding the quantum Hall effect (QHE) in this material. WeExpand
Multiple quantum phases in graphene with enhanced spin-orbit coupling: from the quantum spin Hall regime to the spin Hall effect and a robust metallic state.
These findings not only quantify the detrimental effects of adatom clustering in the formation of the topological state, but also provide evidence for the emergence of spin accumulation at opposite sample edges driven by spin-dependent scattering induced by thallium islands, which eventually results in a minimum bulk conductivity ∼4e²/h, insensitive to localization effects.

Spin Hall effect in AA-stacked bilayer graphene
Abstract The intrinsic spin Hall effect in the AA-stacked bilayer graphene is studied theoretically. The low-energy electronic spectrum for states in the vicinity of the Dirac points is obtained fromExpand
Photoprotected spin Hall effect on graphene with substrate induced Rashbaspin-orbit coupling.
By analyzing the high and intermediate frequency regimes, it is found that in both parameter limits, the spin-Chern number can be tuned by the effective coupling strength of the charge particles to the radiation field and determine the condition for the photoinduced topological phase transition.

Valley polarized quantum Hall effect and topological insulator phase transitions in silicene
It is shown that the combination of an electric field with intrinsic spin orbit interaction leads to quantum phase transitions at the charge neutrality point, providing a tool to experimentally tune the topological state. Expand
