Golden Ratio as Recurrence Operator in Quasicrystal Diffraction and Projection — E8 Intelligence Research
Year: 2026
Type: preprint
Abstract: FINDING: Quasicrystal diffraction indexed via golden ratio basis vectors and higher-dimensional projection methods; golden ratio emerges as a stable local recurrence operator in self-application systems. MATH: - Golden ratio φ = (1+√5)/2 ≈ 1.618, reciprocal 1/φ = φ−1 ≈ 0.618, φ² = φ+1 ≈ 2.618, φ⁻² = 2−φ ≈ 0.382. - Basis vectors for icosahedral quasicrystal indexing: {e₁, e₂, e₃, e₄, e₅, e₆} in 6D, projected to 3D via φ-dependent matrix. - Shechtman's diffraction peaks indexed by integer combinations of φ-scaled reciprocal lattice vectors: Q = Σ nᵢ aᵢ*, with aᵢ* ∝ (1, φ, 0) etc. - Aschheim's golden simplices: elementary 3D tetrahedra with edge ratios 1:φ:φ², tiling quasicrystalline space. - Self-application recurrence: xₙ₊₁ = 1 + 1/xₙ → fixed point φ; reciprocal update rule yields φ as stable attractor. CONNECTION: - Fivefold symmetry forbidden in periodic crystals; quasicrystals use φ-based projection from 6D hypercubic lattice → 3D icosahedral symmetry. - Golden rati Author: Andrew Stewart Caldin, Independent Researcher, UK.
