Magnetic-field-induced spin texture in a quantum wire with linear Dresselhaus spin-orbit coupling
Bibliographic record
Abstract
A quantum wire with strong Rashba spin-orbit interaction is known to exhibit a so-called spin texturing effect in presence of a moderate external magnetic field acting transverse to the wire axis and parallel to the symmetry-breaking ``gate'' electric field causing Rashba interaction. This effect typically disappears when the external magnetic field is made stronger than the effective spin-orbit magnetic field due to the Rashba interaction. In this work, we present a detailed study of the spin texturing phenomenon in a quantum wire with strong linear Dresselhaus spin-orbit interaction and an external transverse magnetic field. Unlike the pure Rashba case, we observe a persistent spin texture even in the limit when the external magnetic field is large and much stronger than the effective spin-orbit magnetic field due to Dresselhaus interaction. Magnetic field dependence of spin texture is therefore an experimentally viable method for identifying the dominant spin-orbit interaction in a zinc-blende quantum wire. We show that the local distribution of the spin density can be modulated by spin-orbit coupling strength, magnetic field, and the Fermi level of the electron gas.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
