We study the bound state spectrum and the conditions for entering a supercritical regime in graphene with strong intrinsic and Rashba spin-orbit interactions within the topological insulator phase. Explicit results are provided for a disk-shaped potential well and for the Coulomb center problem.

We demonstrate that in an inversion-asymmetric quasi-two-dimensional electron system (quasi2DES) with both Rashba and Dresselhaus spin-orbit couplings at present, certain transport directions on which no spin precession occurs can be found when the injected spin is properly polarized. By analyzing the expectation value of spin with respect the injected electron state on each space point in the ...

There is significant current interest in spintronic devices fashioned after a spin analog of the electro-optic modulator proposed by Datta and Das [Appl. Phys. Lett., 56, 665 (1990)]. In their modulator, the “modulation” of the spin polarized current is carried out by tuning the Rashba spin-orbit interaction with a gate voltage. Here, we propose an analogous modulator where the modulation is ca...

We theoretically study the mechanical induction of spin density via Rashba spin--orbit interaction (SOI). The in linear response to lattice distortion dynamics is calculated based on microscopic theory. reveal that there are two mechanisms induction: one acoustic Edelstein effect (AEE) from acceleration and other caused by spin--vorticity coupling (RSVC). find AEE induces a more efficient spin-...

When a foreign atom is placed on a surface of a metal, the surrounding sea of electrons responds by screening the additional charge leading to oscillations or ripples. On surfaces, those electrons are sometimes confined to two-dimensional surface states, whose spin-degeneracy is lifted due to the Rashba effect arising from the spin-orbit interaction of electrons and the inversion asymmetric env...
