Abstract
The origin of superconductivity in the FeSe monolayer on ${\mathrm{SrTiO}}_{3}$ remains one of the unresolved mysteries in condensed-matter physics. Here, by investigation of the temperature evolution of the dynamic charge response of $\mathrm{FeSe}/{\mathrm{SrTiO}}_{3}$, we infer that the response of the monolayer itself is nearly temperature independent. This indicates a constant Fermi surface over a wide range of temperature, in stark contrast to that of the bulk FeSe and other Fe-based superconductors. Our results, which manifest the peculiarity of the electronic structure of the FeSe monolayer, may help for a microscopic understanding of the superconductivity in Fe-chalcogenide monolayers on oxide surfaces in general.

Full frame machine prediction
Teacher imitationNot 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.
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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
