Abstract

fetched live from OpenAlex

Molecular dynamics simulations of a classical asymmetric electron bilayer for various values of the interlayer separation distance $d$ and various degrees of asymmetry have been performed. The number of charged particles in the basic cell of one layer was fixed at 512, corresponding to a coupling strength $\ensuremath{\Gamma}(=\frac{{e}^{2}}{a{k}_{B}T})$ of 80, while that of the other varied from 32 to 512 particles, corresponding to a $\ensuremath{\Gamma}$ of 20 to 80; $a$ is the Wigner-Seitz radius. We have analyzed the intralayer and interlayer pair-correlation functions and the self-diffusion coefficients of the two layers and compared them with those of a symmetric electron bilayer. It is found that the self-diffusion coefficients of the two layers do not differ significantly for values of $d\ensuremath{\le}0.8$ with a marked deviation setting for $d=2$. A fluid-solid phase transition, observed previously for the symmetric bilayer for certain values of $d$, no longer exists even for the slightly asymmetric (512,450) bilayer we considered.

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.
