Attosecond-magnetic-field-pulse generation by electronic currents in bichromatic circularly polarized UV laser fields
Bibliographic record
Abstract
Attosecond-magnetic-field-pulse generation is simulated from numerical solutions of time-dependent Schr\"odinger equations for oriented ${{\mathrm{H}}_{2}}^{+}$. Two schemes with high frequency co- and counter-rotating bichromatic ${\ensuremath{\omega}}_{2}=2{\ensuremath{\omega}}_{1}$ circularly polarized UV laser pulses are investigated. Results show that comparing to single color processes, stronger induced localized magnetic fields $\mathbf{B}$ at the molecular center $O$ $(\mathbf{r}=0)$ are obtained with attosecond duration. This is attributed to frequent recollision and to interference effects of two pathways in photoionization. The induced magnetic fields are shown to be sensitive to (i) the helicity of the combined laser pulses due to different recollision laser-induced electron trajectories and currents, and (ii) also the carrier envelope phases of the combined attosecond laser pulses. The sensitivity of recollision to bichromatic pulses thus allows one to control the induced magnetic-field-pulse 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.
