INFLUENCE OF SPIN-ORBIT INTERACTION ON THE MAGNETOTRANSPORT OF A PERIODICALLY MODULATED TWO-DIMENSIONAL ELECTRON GAS
Bibliographic record
Abstract
Transport properties of a two-dimensional electron gas (2DEG) are studied in the presence of a normal magnetic field B, of a weak one-dimensional (1D) periodic potential modulation V(x)=V 0 cos(Kx), and of the Rashba spin-orbit interaction (SOI) of strength α. For V(x)=0 the SOI mixes the up and down spin states of neighboring Landau levels into two, unequally spaced energy branches. For V(x)≠0 these levels broaden into bands and their bandwidths oscillate with B. The n-th level bandwidth of each series vanishes at different values of B. Relative to the 1D-modulated 2DEG without SOI and one flat-band condition, there are two flat-band conditions that depend on α and the transport coefficients can change considerably. For weak α the Weiss oscillations show beating patterns while for strong α the Shubnikov-de Haas ones are split in two.

How this classification was reachedexpand
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.
