Abstract
We have developed a theory of polariton scattering in the inhomogeneously broadened intersubband transitions in multiple quantum wells and showed that motional narrowing plays an important role in the emission of intersubband polaritons. We then analyzed the results of experiments of intersubband Raman lasing in quantum well structures and showed that the lasing process involves stimulated emission of a polariton comprising a photon, an optical phonon, and an intersubband excitation. Our theory offers an explanation for the abnormally high gain of the parametric process in comparison to optically pumped lasers.

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 it
