چکیده
We theoretically study spin transport in two-or three-dimensional Rashba systems dynamically distorted by surface acoustic waves. The currents the linear response to lattice distortion dynamics are calculated on basis of a microscopic theory combined with local coordinate transformations. As result, we find mechanism direct spin-current generation from not associated charge current or accumulation. Moreover, in-plane helicity generated shear waves via present mechanism. parallel vorticity lattice, and cannot be created conventional methods. Thus, our findings offer an alternative functionality field spintronics.

Equilibrium spin current in graphene with Rashba spin-orbit coupling
The existence of a background spin current under thermodynamic equilibrium is an interesting phenomenon in the two-dimensional electron gas with Rashba spin-orbit coupling (RSOC). Here we study the equilibrium spin current (ESC) in graphene with RSOC. For an infinite graphene with uniform RSOC, we found that the ESC is proportional to λ(2) with λ the Rashba strength and mainly comes from the en...
متن کاملNew generation of two-dimensional spintronic systems realized by coupling of Rashba and Dirac fermions
Intriguing phenomena and novel physics predicted for two-dimensional (2D) systems formed by electrons in Dirac or Rashba states motivate an active search for new materials or combinations of the already revealed ones. Being very promising ingredients in themselves, interplaying Dirac and Rashba systems can provide a base for next generation of spintronics devices, to a considerable extent, by m...
متن کاملMagnetic Helicity Generation by Solar Differential Rotation
Observations of sunspots, active regions, filaments, coronal arcades, and interplanetary magnetic clouds indicate that the Sun preferentially exhibits left-handed, negative-helicity features in its northern hemisphere, and their opposite counterparts in the south, independent of sunspot cycle. We investigate quantitatively the generation of magnetic helicity by solar differential rotation actin...
متن کاملCurrent profile control by alternating current magnetic helicity injection
Current profile control by ac magnetic helicity injection is computationally investigated in a reversed field pinch ~RFP!. Three-dimensional resistive magnetohydrodynamics ~MHD! computation is employed to study the nonlinear MHD. During ac helicity injection, when toroidal and poloidal surface voltages are oscillated out of phase, the parallel electric field is maintained positive over a majori...
متن کاملRashba coupling amplification by a staggered crystal field.
There has been increasing interest in materials where relativistic effects induce non-trivial electronic states with promise for spintronics applications. One example is the splitting of bands with opposite spin chirality produced by the Rashba spin-orbit coupling in asymmetric potentials. Sizable splittings have been hitherto obtained using either heavy elements, where this coupling is intrins...
