Abstract

fetched live from OpenAlex

We develop a simple analytical theory for the study of coherent control of radiationless transitions, and in particular, internal conversion leading to dissociation, in molecules possessing overlapping resonances. The method is applied to a model diatomic system. In contrast to previous studies, we consider here the control of a molecule that is allowed to decay during and after the preparation process. We use this theory to derive the shape of the laser pulse that creates the specific excited wave packet that best enhances or suppresses the radiationless transitions process. The results show the importance of resonance overlap in the molecule in order to achieve efficient coherent control over radiationless transitions via laser excitation. Specifically, resonance overlap is proven to be crucial in order to alter interference contributions to the controlled observable, and hence to achieve efficient coherent control by varying the phase of the laser field.

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.
