Abstract
We present microwave and infrared measurements on ${\mathrm{SmLa}}_{0.8}{\mathrm{Sr}}_{0.2}{\mathrm{CuO}}_{4\ensuremath{-}\ensuremath{\delta}}$, which are direct evidence for the existence of a transverse optical plasma mode, observed as a peak in the $c$-axis optical conductivity. This mode appears as a consequence of the existence of two different intrinsic Josephson couplings between the ${\mathrm{CuO}}_{2}$ layers, one with a ${\mathrm{Sm}}_{2}{\mathrm{O}}_{2}$ block layer, and the other one with a $(\mathrm{La},\mathrm{Sr}{)}_{2}{\mathrm{O}}_{2\ensuremath{-}\ensuremath{\delta}}$ block layer. From the frequencies and the intensities of the collective modes we determine the value of the compressibility of the two dimensional electron fluid in the copper oxygen planes.

How this classification was reachedexpand
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.
