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 distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
