Abstract
We study scattering properties of the discrete Laplacian H on the half-space Z+d+1=Zd×Z+ with the boundary condition ψ(n,−1)=λ tan(πα⋅n+θ)ψ(n,0), where α∈[0,1]d. We denote by H0 the Dirichlet Laplacian on Z+d+1. Khoruzenko and Pastur [Phys. Rep. 288, 109–126 (1997)] have shown that if α has typical Diophantine properties then the spectrum of H on R\σ(H0) is pure point and that corresponding eigenfunctions decay exponentially. We demonstrated in an earlier paper [Lett. Math. Phys. 45, 185 (1998)] that for every α independent over the rationals the spectrum of H on σ(H0) is purely absolutely continuous. In this paper, we continue the analysis of H on σ(H0) and prove that whenever α is independent over the rationals, the wave operators Ω±(H,H0) exist and are complete on σ(H0). Moreover, we show that under the same conditions H has no surface states on σ(H0).

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.
