We investigate the quantum adiabatic pumping effect in an interferometer attached to two one-dimensional leads. The interferometer is subjected to an Aharonov-Bohm flux and Rashba-Dresselhaus spin-orbit interaction. Using Brouwer’s formula and rigorous scattering eigenstates, we obtained the general closed formula for the pumping Berry curvatures depending on spin for general interferometers when the external control parameters only modulate the scattering eigenstates and corresponding eigenvalues. In this situation, pumping effect is absent in the combination of the control parameters of Aharonov-Bohm flux and spin-orbit interaction strength. We have shown that finite pumping is possible by modulating both Rashba and Dresselhaus interaction strengths and explicitly demonstrated the spin-pumping effect in a diamond-shaped interferometer made of four sites.

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.
