Abstract

fetched live from OpenAlex

We present measurements of the polarized optical spectra of ${\mathrm{NaV}}_{2}{\mathrm{O}}_{5}$ and ${\mathrm{LiV}}_{2}{\mathrm{O}}_{5}.$ In an energy range from 0.5 to 5.5 eV, we observe similar peaks in the $E\ensuremath{\Vert}a$ spectra of ${\mathrm{NaV}}_{2}{\mathrm{O}}_{5}$ and ${\mathrm{LiV}}_{2}{\mathrm{O}}_{5},$ which suggests similar electronic structures along the a axis in both materials. On the other hand, we find an almost complete suppression of the peaks in ${\ensuremath{\sigma}}_{b}$ of ${\mathrm{LiV}}_{2}{\mathrm{O}}_{5}$ around 1 and 5 eV. We attribute this suppression to the charge localization effect originating from the existence of a double-chain charge-ordering pattern in ${\mathrm{LiV}}_{2}{\mathrm{O}}_{5}.$

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
