Abstract
The dynamics of a hydrogen atom in a spherical box under the action of a strong infrared femtosecond laser is numerically investigated. The spherical box is introduced to model collisions of ionized electrons with neighboring atoms to model their influence on high-order harmonic generation. The physical situation appropriate for such application is considered in detail. The presence of tunneling in the process is investigated. In the strong field limit this consideration is extended including a dressing approach in the calculation. The harmonic spectrum is calculated for a small radius of the sphere assuming a high gas pressure. The intensities of the harmonic lines are reduced and the envelope of the spectrum is strongly modified with respect to the plateau of harmonics. The inclusion of the dressing approach in the calculation can significantly modify this result. The situation is changed if a kicking electric field is added at the moment when ionization probability has local maximum. The electron kinetic energy is drastically increased, and as a consequence of the dynamic Stark shifts in the kicking field, and an unusual electron recombination is possible. The odd harmonics of a very high-order and a somewhat different form of plateau of harmonics appear. The intensities of so obtained single-atom harmonic emission are dramatically enhanced. To check the reliability of the model with an impenetrable spherical box, high-pressure argon gas is also considered in relation to the single atom high-order harmonic generation.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
