🟢 TightBinding1D/MassGap/Infinite

Provisional v2 view — RES not wired

Generated by docs/atlas/generate.jl — a pure VIEW over the *_registry.jl claims + the static test/INVENTORY.jsonl AST scan. No test is executed and no src is run; test/INVENTORY.jsonl is regenerated in-place (idempotently) from that static scan; fetch/@register untouched. Assurance labels are PROVISIONAL: residuals / confidence are not shown yet (RES not wired). Badges reflect the committed test AST, not the latest CI run — a hub can read green while its @test is red between regenerations. @sweep = a graceful regime-resolution gap, not card omission.

Assurance level: corroborated-at-p

Independently corroborated. See the cards below.

src claim

  • method analytic, reliability high, refs: Ashcroft-Mermin 1976
  • Ī” = max(0, |μ| - 2t); gapless for |μ| ≤ 2t (metallic).

Test calls

The exact verify(...) call the harness executed for this hub (reconstructed from the test AST):

verify(TightBinding1D(; t = 1.0, μ = 3.0), MassGap(), Infinite(); route = :second_closed_form, independent = 1.0, agree_within = 1.0e-9, refs = ["Band insulator mu > 2t: gap = |mu| - 2t"])
verify(TightBinding1D(; t = 1.0, μ = 0.0), MassGap(), Infinite(); route = :second_closed_form, independent = 0.0, agree_within = 1.0e-10, refs = ["Half filling: gapless Fermi surface"])

Assurance (provisional)

  • level: corroborated-at-p 🟢
  • cards: 2 Ā· model ED-feasible
  • RES not wired — measured residuals / confidence are not shown yet.
