Abstract

fetched live from OpenAlex

We investigate the combined influence of superexchange and electron-phonon interactions on the excitation spectra and on hole propagation in a ferromagnetic plane of ${\mathrm{LaMnO}}_{3}.$ The Jahn-Teller effect modifies the energies of both orbital and phonon excitations and can lead to modes with mixed character, and for strong Jahn-Teller interaction even to a structural instability due to profound softening of one of the phonon modes. Solving the problem of hole propagation in the self-consistent Born approximation, we found that the quasiparticle states at the bottom of the spectrum are accompanied by broad structures, representing vibrational side bands which result from the hole-lattice coupling.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
