Abstract

fetched live from OpenAlex

We report on a quadratic electroabsorption measurement of the electronic third-order molecular susceptibility of silicon phthalocyanine-monomethacrylate-doped poly(methyl methacrylate) thin films. The results are compared with homogeneously broadened (Lorentzian) and inhomogeneously broadened theories of the second hyperpolarizability. For the first time to our knowledge the effect of distribution of sites in the polymer is taken into account and is found to be negligible on its effects on chi(3). We show that a three-level model of the third-order susceptibility is sufficient to characterize the electronic states of these dye-doped thin films in the visible regime. The limited spectral range of the experiment allows us to estimate only the zero-frequency third-order molecular susceptibility, which we find is below the quantum-mechanical limit.

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.
