Abstract

fetched live from OpenAlex

We have investigated far-infrared excitations in rectangular arrays of antidots in modulation-doped ${\mathrm{Al}}_{x}{\mathrm{Ga}}_{1\ensuremath{-}x}\mathrm{As}\ensuremath{-}\mathrm{GaAs}$ heterostructures. In the rectangular antidot lattice the degeneracy of modes of a square array is lifted and a rich spectrum of higher-frequency modes is excited, particularly at small magnetic fields. These modes are sensitive to the direction of linear polarized radiation. Our experimental results are compared with theoretical calculations based on the Thomas--Fermi--Dirac--von Weizs\"acker hydrodynamic theory.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
