Attosecond-magnetic-field-pulse generation by coherent circular molecular electron wave packets
Bibliographic record
Abstract
Attosecond-magnetic-field-pulse generation is investigated using numerical solutions of the time-dependent Schr\"odinger equation for oriented ${{\mathrm{H}}_{2}}^{+}$ excited and ionized by intense $2\ifmmode\times\else\texttimes\fi{}{10}^{16} \mathrm{W}/{\mathrm{cm}}^{2}$ circularly polarized attosecond UV pulses. The results show that localized attosecond-magnetic-field pulses $B$ at the molecular center $(\mathbf{r}=\mathbf{0})$ decrease in intensity with increasing attosecond-pulse wavelength, following a classical model. Magnetic-field minima are obtained at a specific laser-pulse wavelength $\ensuremath{\lambda}=55$ nm, which is attributed to ionization suppression. It is found that spatially localized coherent circular electron currents and wave packets are created and induce magnetic-field minima. At $\ensuremath{\lambda}=55$ nm, coherent excitation between the ground state and Rydberg states is created, giving rise to partial Rabi oscillations in population and doublets in molecular above-threshold-ionization photoelectron energy spectra. Pulse intensities are shown to influence these effects on the attosecond time scale through population variations.

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.
