Abstract

fetched live from OpenAlex

We investigate Klein tunneling for the $\ensuremath{\alpha}\text{\ensuremath{-}}{T}_{3}$ model, which interpolates between graphene and the dice lattice via parameter $\ensuremath{\alpha}$. We study transmission across two types of electrostatic interfaces: sharp potential steps and sharp potential barriers. We find both interfaces to be perfectly transparent for normal incidence for the full range of the parameter $\ensuremath{\alpha}$ for both interfaces. For other angles of incidence, we find that transmission is enhanced with increasing $\ensuremath{\alpha}$. For the dice lattice, we find perfect, all-angle transmission across a potential step for incoming electrons with energy equal to half of the height of the potential step. This is analogous to the ``super'', all-angle transmission reported for the dice lattice for Klein tunneling across a potential barrier.

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.
