Scheme for coherently quenching resonant current in a three‐level quantum dot energy level mixer
Bibliographic record
Abstract
Abstract We outline a scheme to create a “dark” state by three‐level mixing that is potentially a useful tool for quantum coherent transport. Magnetic‐field‐induced intra‐dot level mixing can lead to rich quantum superposition phenomena between three approaching single‐particle states in a quantum dot when probed by the ground state of an adjacent weakly coupled quantum dot in the single‐electron resonant tunnelling regime. The mixing relies on non‐negligible anharmonicity and anisotropy in confining potentials of realistic quantum dots. Anti‐crossing and transfer of strengths between resonances can be understood with a simple coherent level mixing model. Superposition can lead to the formation of a dark state by complete cancellation of an otherwise strong resonance. This is an all‐electrical analogue of coherent population trapping seen in three‐level‐systems from quantum and atom optics. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

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.
