Abstract

fetched live from OpenAlex

We report a theoretical investigation of the Kondo effect in a quantum dot (QD) molecule, where a larger QD supports multiple transmission channels and a smaller side-coupled QD acts as the Kondo impurity. The conductance can be completely suppressed by Kondo scattering when there is only one transport channel; but for multiple channels the conductance is partially recovered when channel level spacing is comparable to the coupling strength to the leads. A competition of bonding of states in the two QD with the Kondo resonance results to an oscillatory behavior of conductance as a function of gate voltage.

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.

Not 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.
