Vortex interactions in a thin platelet superconductor
Bibliographic record
Abstract
The thermal fluctuations of vortices in a superconductor can be usefully mapped onto the quantum fluctuations of a collection of bosons at T = 0 moving in two dimensions. When the superconductor is a thin platelet with the magnetic field parallel to its surface, the interacting quantum bosons are effectively moving in one dimension, allowing for powerful Tomonaga–Luttinger liquid methods to be applied. Here we consider how this one-dimensional limit is approached, studying the interaction of vortices with the platelet surfaces and each other. Using realistic parameters and vortex interactions for an underdoped YBCO (yttrium–barium–copper oxide) platelet we determine the scattering length, a , characterizing the low energy interaction of a vortex pair as a function of the platelet thickness. a determines the Luttinger parameter, g , for the quantum system at low densities, n 0 : .

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.
