Abstract
Perimeter Institute for Theoretical PhysicsWaterloo, Ontario, N2L 2Y5, Canada.Dipartimento di Fisica, Universita di MilanoAs a novelapproachwith possible relevance to semiclassical gravity, we proposeto define regionsof space as quantum subsystems. After recalling how to divide a generic quantum system into“parts”, we apply this idea to a free scalar field in Minkowski space and we compare two differentlocalization schemes. The first scheme is the standard one, i nduced by the local relativistic fields;the alternative scheme that we consider is the one induced by the Newton-Wigner operators.If degrees of freedom are divided according to the latter, the Hamiltonian of the field exhibitsa certain amount of non-locality. Moreover, when a region ofspace is cut off from the restaccording to the Newton-Wigner scheme, the geometric entropy is finite and exhibits a sensiblethermodynamic behaviour.From Quantum to Emergent Gravity: Theory and PhenomenologyJune 11-15 2007Trieste, Italy

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.
