Abstract
The optical injection of spin, current, and spin current in bulk Ge is investigated theoretically. Spin-polarized carriers can be photoexcited by monochromatic circularly polarized light through either one- or two-photon processes. With simultaneous $\ensuremath{\omega}$ and $2\ensuremath{\omega}$ irradiation, currents can be injected and coherently controlled by interference of one- and two-photon transition amplitudes. We calculate the spectral dependence of these all-optical effects, including anisotropy and dichroism effects and a careful description of the hole spin injection. Injection at the ${E}_{1}$ resonance is studied thanks to an adaptive grid and a full-zone $\mathbf{k}\ensuremath{\cdot}\mathbf{p}$ band structure.

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; both teacher heads agree on what is shown here.
