Abstract

fetched live from OpenAlex

Abstract In the present study, we develop a kinetic lattice gas model for hopping in an inhomogeneous one‐dimensional adsorbate system with nearest‐neighbor interactions and periodic boundary conditions. From the matrices of the associated equations of motion, we can calculate adsorbate correlation functions in momentum space exactly on all time and length scales. The corresponding eigenvalues and eigenvectors in the long‐time, long‐wavelength limit yield the diffusion coefficient. We analyze its dependence on coverage and temperature and compare our results with earlier analytic work for this model. Our approach is readily extendable to two‐dimensional systems. © 2006 Wiley Periodicals, Inc. Int J Quantum Chem, 2006

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.
