Quantum work extraction of an accelerated Unruh-DeWitt battery in relativistic motion
Bibliographic record
Abstract
We investigate the maximal amount of quantum work in a driven atom as a quantum battery which is coupled to a massless scalar field in a Minkowski vacuum. The relativistic thermodynamics of the quantum battery is explored from the prospective of quantum channels. It is found that quantum work extraction can be enhanced in the battery whose trajectory is characterized by a combination of a linear accelerated motion and a component of the four velocity. In the nonrelativistic case, the accelerated motion results in the attenuation of energy extraction, while the velocity component can prevent the degradation of quantum work to a certain extent. The work extraction can increase in the relativistic regime. Moreover, for ultrarelativistic velocities, the relativistic thermodynamics of the quantum battery can behave as if it were a closed system owing to the relativity correction associated with the velocity. The extractable work can be shielded from the impacts of vacuum fluctuations and relativistic motion. It is demonstrated that the work extraction relies on quantum coherence of the relativistic battery and nonclassical nature in the Minkowski vacuum.

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.
