Abstract

fetched live from OpenAlex

The three-dimensional time-dependent Schr\"odinger equation is solved exactly for the ${\mathrm{H}}_{2}^{+}$ molecular ion as a function of internuclear distance R in a short intense laser field pulse and a static magnetic field, parallel to the internuclear axis, using a numerical integration method. Previous calculations of laser-induced ionization in this ion for zero magnetic field [Phys. Rev. A 48, 3837 (1993); 52, 2511 (1995)] demonstrated the phenomenon of charge-resonance-enhanced ionization (CREI) at critical distances ${R}_{c},$ due to Stark displacements of the lowest unoccupied molecular orbital (LUMO) above internal proton Coulomb and static laser field barriers. The presence of the magnetic field allows for controlling the energy displacements of the LUMO and consequently control of CREI, thus confirming CREI as a quasistatic electron tunneling process in the nonsymmetric double-well potential created by protons and a laser field.

Full frame distilled prediction

Teacher imitation

Not 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.
