Abstract

fetched live from OpenAlex

Abstract We investigate the entanglement content of a free, light scalar field theory in the Bunch–Davies vacuum within the cosmological patch of de Sitter spacetime, focusing on how entanglement varies with the Hubble rate H . We find that the entanglement between any spacelike-separated pair of field modes localized in finite regions decreases as H increases. This occurs despite the fact that correlations between such local modes increase with H . Consequently, these correlations do not contribute to entanglement. Our analysis elucidates how entanglement is distributed in de Sitter space and demonstrates that localized field modes at the end of inflation are less entangled than they would be in the Minkowski vacuum of flat spacetime.

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.
