Quantum coherence of a circularly accelerated atom in a spacetime with a reflecting boundary
Bibliographic record
Abstract
Abstract We investigate, in the paradigm of open quantum systems, the dynamics of quantum coherence of a circularly accelerated atom coupled to a bath of vacuum fluctuating massless scalar field in a spacetime with a reflecting boundary. The master equation that governs the system evolution is derived. It is found that the quantum coherence diminishes to zero with increasing centripetal acceleration and evolution time in the case without a boundary. However, the presence of a boundary will modify the quantum fluctuations of the scalar field, which results in the enhancement of quantum coherence near the boundary compared with that for the unbounded case. Particularly, when the atom is very close to the boundary, although the atom still interacts with the environment, it behaves as if it were a closed system as a consequence of the presence of the boundary, and the quantum coherence can be shielded from the effect of the vacuum fluctuating scalar field.PACS numbers: 03.65.Yz, 03.67.Mn, 03.65.Ta

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.
