Abstract
Analysis of the dynamic structure factors of strongly coupled classical, symmetric electronic bilayers obtained from molecular dynamics simulation confirms the existence of two longitudinal collective modes. The in-phase mode resembles the optical mode seen in single-layer two-dimensional systems, while the out-of-phase mode shows an energy gap at wave numbers $\stackrel{\ensuremath{\rightarrow}}{q}0$ for interlayer separations $d$ less than about 1.5 (in units of the Wigner-Seitz radius). These dispersion results corroborate recent molecular dynamics data obtained using a different algorithm and analysis, and for a lower value of the plasma parameter \ensuremath{\Gamma}. The energy gap is seen not to be very sensitive to the value of \ensuremath{\Gamma}. The analysis of our data has brought out an interesting feature: a bifurcation of the out-of-phase dispersion curve for a high value of $\ensuremath{\Gamma}(=80)$ for intermediate values of $d.$ This feature is not seen for lower values of $\ensuremath{\Gamma}(=40)$ and has not been predicted by any theoretical model.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
