Abstract

fetched live from OpenAlex

Nous entendons par gaz de Bose unitaire un système composé de bosons sans spin interagissant dans l'onde s par un potentiel de longueur de diffusion infinie et de portée (réelle ou effective) presque négligeable, système pour l'instant abstrait mais dont la tentative de réalisation avec des atomes froids est en cours. À partir de la solution analytique connue du problème à trois corps dans un piège harmonique, et de méthodes précédemment développées pour des fermions, nous déterminons le troisième cumulant b 3 , puis le troisième coefficient du viriel a 3 de ce gaz, dans le cas spatialement homogène, en fonction de sa température et du paramètre à trois corps R t caractérisant l'effet Efimov. Un point marquant est qu'en convertissant des séries en des intégrales (par une méthode des résidus inverse), puis en utilisant un petit paramètre inattendu, l'angle de masse ν = π/6 des trois bosons, on peut pousser l'estimation complètement analytique de b 3 et de a 3 jusqu'à une erreur en pratique négligeable.

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.
