We derive the effective dimensionally reduced Schrödinger equation with spin–orbit interaction (SOI) in low-dimensional electronic strain-driven nanostructures. By employing a method of adiabatic separation among fast normal quantum degrees of freedom and slow tangential quantum degrees of freedom, we show the emergence of a strain-induced Rashba-like SOI. By applying this analysis to one-dimensional (1D) curved quantum wires we demonstrate that the curvature-induced Rashba SOI leads to enhanced spin–orbit effects.

To consider the contribution of the spin–orbit interaction in the extraordinary wave spectrum we derive a generalization of the separate spin evolution quantum hydrodynamics. Applying the corresponding nonlinear Pauli equation we include the Fermi spin current contribution in the spin evolution. We find that the spectrum of extraordinary waves consists of three branches: two of them are well-known extraordinary waves and the third one is the spin-electron acoustic wave. A change of the extraordinary wave spectrum due to the spin–orbit interaction is also obtained.
