Abstract
The photoluminescence emission intensities of the exciton states in $\mathrm{In}\mathrm{As}∕\mathrm{Ga}\mathrm{As}$ coupled quantum dots are studied with regard to the tunneling-induced dependence on splitting energy. Even at very low excitation, emission from bonding and antibonding states is observed, as long as the splitting ranges between a few and $\ensuremath{\sim}30\phantom{\rule{0.3em}{0ex}}\mathrm{meV}$. As the splitting is dominated by the conduction band states, this demonstrates an acoustic-phonon relaxation bottleneck for electrons. For larger splittings, only bonding state emission is observed at low excitation, indicating fast carrier relaxation, which is most likely caused by a combination of electron-hole scattering and polaron formation.

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
