Abstract
3D topological insulators are metallic conductors at their interface with a conventional insulator, sharing some electronic properties with graphene.These surface (or interface) states are 2D Dirac fermions with a spin chirality of the Dirac cones, due to a strong spin-orbit coupling.In high-quality nanostructures, as obtained by the Vapor-Solid method, this leads to specific transport properties which can be evidenced by quantum transport measurements, with an energy resolution of a few μeV.One of our recent achievements is the first demonstration of the quasi-ballistic transport of spin-chiral Dirac fermions in a Bi 2 Se 3 nanowire, as evidenced by the study of decoherence at very low temperatures.Such a finding shows the potent of spin-chiral 2D Dirac fermions in a 3D topological insulator to investigate quantum coherent transport in the weak-coupling limit to their environment, a situation otherwise only accessible with edge states in the Integer Quantum Hall regime of a AlGaAs high-mobility 2D electro n gas.

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.
