The foundational papers are: + +1. **Huse, D.A.** "Interfacial shape transitions in the chiral clock model" + *Phys. Rev. B* **24**, 2643 (1981). — Introduces the chiral clock model, + the chirality parameter δ that breaks left-right symmetry, and the + commensurate-incommensurate transition. + +2. **Ostlund, S.** "Incommensurate and commensurate phases in chiral clock + models" *Phys. Rev. B* **24**, 398 (1981). — Independent introduction; + the phase diagram (ferromagnetic → floating/incommensurate → paramagnetic). + +3. **Huse, D.A. and Fisher, M.E.** "Domain wall dynamics in chiral clock + models" *Phys. Rev. B* **25**, 3241 (1982). — Domain wall analysis; + the floating phase has algebraic (power-law) correlations. + +4. **Yeomans, J.M. and Fisher, M.E.** "Commensurate-incommensurate + transitions in chiral clock models" *J. Phys. C* **14**, L273 (1981). + — Mean-field and scaling analysis of the CI transition. + +5. **Selke, W. and Huse, D.A.** "Monte Carlo studies of the chiral clock + model" *Phys. Rev.

The coupling now depends on the DIRECTION +of the spin difference (clockwise vs counterclockwise on the Z_N dial). + +### The N=4 Case (SilverSight) + +For N=4, the spins are s_i ∈ {0, 1, 2, 3}, corresponding to the 4th roots +of unity {1, i, -1, -i}. The coupling is: + + H = -J Σ_{} cos(π(s_i - s_j - δ_{ij}) / 2) + +The four possible spin differences and their energies (at δ=0): + +| s_i - s_j | cos(π·Δ/2) | Coupling type | Physical meaning | +|---|---|---|---| +| 0 | +1 | Ferromagnetic | Spins aligned (over-crossing) | +| 1 | 0 | Decoupled | No interaction (achiral) | +| 2 | -1 | Antiferromagnetic | Spins anti-aligned (under-crossing) | +| 3 | 0 | Decoupled | No interaction (achiral) | + +With chirality δ_{ij} ≠ 0, the table shifts: +- δ=1: the "aligned" state becomes s_i - s_j = 1 (chiral spiral) +- δ=2: ferromagnetic ↔ antiferromagnetic swap +- δ=3: chiral spiral in the opposite direction + +### Phase Diagram (Huse-Ostlund, 1981) + +The chiral clock model at N=4 has three phases: + +1. **Commensurate (ferromagnetic):** δ < δ_c₁. Ground state is aligned + (all spins equal). Unique ground state. EASY for optimization. + +2. **Floating (incommensurate):** δ_c₁ < δ < δ_c₂. Ground state is a + chiral spiral with irrational pitch. Algebraic correlations. + **Hardest for optimization** — the ground state is non-trivial + and the energy landscape is rugged. + +3. **Paramagnetic (disordered):** δ > δ_c₂. No long-range order. + Many low-energy states. EASY for optimization (many solutions). + +The **floating phase is the QAOA hardness peak** — this is the +physics-based prediction for where QAOA should be hardest. + +### Connection to the SilverSight Chiral Labels + +The SilverSight chiral labels map directly to Z_4 clock spins: + +| Chiral label | Z_4 spin | Root of unity | Coupling sign (δ=0) | +|---|---|---|---| +| achiral_stable (a mod 4 = 0) | s = 0 | 1 | Decoupled (Δ=1 or 3 → cos=0) | +| left_handed (a mod 4 = 1) | s = 1 | i | Ferromagnetic (Δ=0 → cos=+1) | +| right_handed (a mod 4 = 2) | s = 2 | -1 | Antiferromagnetic (Δ=2 → cos=-1) | +| chiral_scarred (a mod 4 = 3) | s = 3 | -i | Decoupled (Δ=1 or 3 → cos=0) | + +The **chirality δ_{ij}** is determined by the PAIR of chiral labels: + δ_{ij} = (s_i - s_j) mod 4 (the clock difference itself IS the chirality) + +This means: the Sidon address structure (mod 4) determines BOTH the +spin values AND the chirality. The Sidon set is not just a lattice — +it's a **chiral clock lattice** where the chirality pattern is +determined by the number-theoretic structure of the addresses. + +### The Commensurate-Incommensurate Transition + +The key physics prediction: as the Sidon set changes (different mod n, +different address spacings), the **effective chirality** changes. Some +Sidon sets are in the commensurate phase (easy), some in the floating +phase (hard), some in the paramagnetic phase (easy). + +This is the **physics-based second axis** that T39 was looking for: +- **Drift (β)**: coupling magnitude (intra-set, T39's r=-0.82) +- **Effective chirality (δ)**: determined by the Sidon set's mod-4 + structure (inter-set, the new axis) + +The T39 finding (drift predicts QAOA, r=-0.82) measured the INTRA-set +variation (fixed Sidon set, varying β). The INTER-set variation +(different Sidon sets, fixed β) is governed by the effective chirality +— which phase of the chiral clock model each set falls into. + +## The Reformulated Model + +### Definition + +The SilverSight chiral clock model on a Sidon set S = {a₁, ..., aₙ} in Z_m: + +``` +H = -Σ_{i} Re(q_i⁻¹ · J_ij · q_j), q_i ∈ S³ + + J_ij = log(a_i + a_j) · n̂_ij^Hopf (Baker-weighted Hopf coupling) + + QAOA projection: Z₂⁴ Ashkin-Teller (4 independent binary spins per site) + + CRITICAL DOMAIN NOTE: + For ℕ-valued addresses, arg(a_i + i·a_j) ∈ [0, π/2) — always positive. + Frustration requires ℤ-valued (signed) addresses, where the Gaussian + argument can fall in [π, 2π) producing antiferromagnetic couplings. + The SilverSight model uses ℤ-valued Sidon sets (addresses can be negative) + to ensure the chiral angle has full 360° range. + + Connection to existing SilverSight: + - HopfFibration.lean: Quaternion structure, chiral labels → {1,i,j,k} + - BraidCross.lean: Z₂ XOR crossing slots → Z₂⁴ block structure + - YangBaxter.lean: R₁₂R₁₃R₂₃ = R₂₃R₁₃R₁₂ (integrability preserved) + - CartanConnection.lean: NR bracket [μ,μ]=0 (Sidon block-diagonal) +-/ + +import Mathlib.Analysis.SpecialFunctions.Log.Basic +import Mathlib.Analysis.SpecialFunctions.Trigonometric.Basic +import Mathlib.Tactic + +namespace SilverSight.ChiralClockModel + +-- ── Core types ──────────────────────────────────────────────────────── + +/-- A signed Sidon address in Z_n.
