Abstract

fetched live from OpenAlex

Quantum time dilation occurs when a clock moves in a superposition of relativistic momentum wave packets.The lifetime of an excited hydrogenlike atom can be used as a clock, which we use to demonstrate how quantum time dilation manifests in a spontaneous emission process.The resulting emission rate differs when compared with the emission rate of an atom prepared in a mixture of momentum wave packets at order v 2 /c 2 .This effect is accompanied by a quantum correction to the Doppler shift due to the coherence between momentum wave packets.This quantum Doppler shift affects the spectral line shape at order v/c.However, its effect on the decay rate is suppressed when compared with the effect of quantum time dilation.We argue that spectroscopic experiments offer a technologically feasible platform to explore the effects of quantum time dilation.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
