Furthermore, due to the absence of spin-flip (e.g., Rashba-like spin-orbital coupling) terms, the physical spin Sz is preserved and the system can be decoupled into two components with opposite Sz . This makes the two spindepende ...

We study the spin edge states, induced by the combined effect of spin-orbit interaction (SOI) and nonhomogeneous magnetic field, exposed perpendicularly to one- and two-dimensional electron systems.

Spin Angular Momentum and the Dirac Equation
... The divergence of displacement is ∂x ax + ∂y ay = 2(cos ϕ − 1), which is not zero in general. The theory of elastic waves could be improved by including higher-order deriatives, [8] but this does not solve the fundamental limitation to small displacements. Instead we use a different approach based on ...
