Square-wave, spin-dependent transmission through periodically stubbed electron waveguides
Bibliographic record
Abstract
We study spin‐dependent electron transmission T through waveguides (WGs) with periodically varied width c and strength α of the spin‐orbit interaction. c is varied by attaching stubs to the WG, and α by applying gates. T can exhibit a nearly square‐wave behavior as a function of the stub dimensions, of α, of the length of the gated subunit, and of the incident energy if only one mode propagates in the WG. If mode mixing is allowed the results become more complex but remain qualitatively the same. The transmission through a superlattice, with alternating segments of lengths l1, l2, and strengths α1, α2, is a periodic function of αj and lj, j = 1, 2. By simultaneously varying c and α one can very effectively control the gaps in the transmission, make them square and wide, block either spin state, and select the outgoing spin state.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
