Abstract

fetched live from OpenAlex

Coherent optical and acoustic phonons are observed in strongly confined CdSe quantum dots using excitonic state--resolved femtosecond pump/probe experiments. These state-resolved time-domain experiments yield the size dependent exciton-phonon couplings for both modes as well as the excitonic state dependent couplings. The size dependences are weak in this regime, but the state dependence is large for the optical phonons via the Fr\"ohlich interaction. The state dependent coupling to optical phonons suggests that the exciton becomes less polar for higher states. The time-domain data are compared to frequency-domain resonance Raman data. The differences between the various experimental results are discussed in terms of intrinsic versus extrinsic coupling and quantified in terms of the state dependent exciton-phonon couplings.

Full frame distilled prediction

Teacher imitation

Not 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.
