Abstract

FINDING: No direct evidence of quantum dimension sqrt(6) or golden ratio squared 2.618 in toric code anyon fusion from provided sources. Toric code anyons (e, m, ε) have quantum dimensions 1, 1, √2 respectively; golden ratio appears in Fibonacci anyon models, not toric code. MATH: Toric code anyon quantum dimensions: d_e = 1, d_m = 1, d_ε = √2. Total quantum dimension D = √(1² + 1² + (√2)²) = √4 = 2. No sqrt(6) or 2.618 present. CONNECTION: √2 relates to square lattice symmetry (crystallographic group p4m), not golden ratio. Toric code is defined on square lattice with Z₂ gauge theory — no base-60 or pentagonal symmetry. DEPTH: 1 — The search query's hypothesized constants (sqrt(6), 2.618) are absent from toric code. The provided sources do not support the claimed connection. Toric code is a distinct topological order from Fibonacci anyon models where golden ratio appears. Author: Andrew Stewart Caldin, Independent Researcher, UK.
