OP-SD-004 · Continuum-to-Microscopic Correspondence

The equal-connection FCC scalar model has a full-wave-number cosine dispersion, second moment and long-wave expansion. Continuous-time lattice propagation, the full multicomponent field and feedback-renormalized speeds are different checks. This review finds that Eq. (5.1.11), its following half-angle form and fourth-order expansion cannot all be identical with their printed coefficients; the FCC page records the specific difference.

The equal-connection FCC scalar model has a full-wave-number cosine dispersion, second moment and long-wave expansion. Continuous-time lattice propagation, the full multicomponent field and feedback-renormalized speeds are different checks. This review finds that Eq. (5.1.11), its following half-angle form and fourth-order expansion cannot all be identical with their printed coefficients; the FCC page records the specific difference.

Mathematical result
Twelve neighbours, four sign combinations per group; a geometric result.

Mathematical result
Equal-link scalar/selected-polarization channel, Γ₀>0 and c²=Γ₀a₀². Uses the full cosine spectrum (5.1.11)/(4.12); the printed half-angle coefficient preceding (5.1.12) is 2 rather than the equivalent 4, recorded locally.

02Research still required

First sum every neighbour and expand with one coefficient convention, retaining manuscript equation numbers and reporting the discrepancy instead of silently replacing it. Then derive all branches, coarse-graining weights and error orders from the full connection law, testing projection mixing in nonuniform backgrounds and microscopic refresh fronts.

03The next reproducible deliverable

Deliver a reproducible neighbour table, dynamical matrix, inter-equation coefficient check and reviewable correction options; only then provide coefficient-dependent dispersion plots, domains and directional experimental response.

04Scope and research links

High symmetry does not replace connection dynamics; second-order isotropy does not imply isotropy at every wave number, and finite adjacency in continuous time does not automatically give a strictly zero-response light cone.
