The Elusive Golden Ratio: A Search for the Englert-Greenberger-Yasin Duality Relation — E8 Intelligence Research

Published Oct 7, 2026• 0 citations
Publisher

Abstract

FINDING: The search results are largely pedagogical (YouTube lectures, MIT OCW, Perimeter Institute) and do not contain a specific research paper on the Englert-Greenberger-Yasin duality relation or its golden-ratio connection. The only substantive academic item is an arXiv preprint (2601.15314v1) on cognitive complementarity, which is philosophical, not mathematical. MATH: No new equations, constants, or ratios are presented in the raw findings. The E-G-Y duality relation itself (which is *not* extracted here) is: \( \mathcal{V}^2 + \mathcal{D}^2 \leq 1 \) where \( \mathcal{V} \) is fringe visibility and \( \mathcal{D} \) is which-path distinguishability. This is the standard complementarity bound. No golden-ratio or base-60 constants appear in the provided text. CONNECTION: The only geometric link is *graph duality* (Euler's formula \( V - E + F = 2 \)) in the planar graph video — but this is unrelated to quantum complementarity.

Absence of Golden Ratio in Quantum Interference Literature — E8 Intelligence Research

Andrew Stewart Caldin

FINDING: The search results are dominated by popular-science videos (BBC, PBS, Perimeter Institute) and one arXiv paper on variational QFT — none of which contain the specific claim of "golden ratio in quantum interference phase 36° decision theory." The only substantive mathematical item is the arXiv paper (hep-th/9707234v2), which is about Gaussian approximation in QFT, not golden ratios or consciousness. MATH: No new equations, constants, or ratios are extractable from the video titles/descriptions. The arXiv paper contains standard variational QFT formalism (functional Schrödinger picture, Gaussian effective potential) — no golden ratio, no 36°, no decision theory. The only constants implied are generic (π, ℏ, etc.) from QFT context. CONNECTION: Zero direct connection to 0.382, 0.618, 0.786, 1.618, 2.618, base-60, or crystallographic symmetries. The video "The Golden Ratio Was Found Inside a Quantum System" is a title only — no mathematical content accessible. The 36° angle (whic Author: Andrew Stewart Caldin, Independent Researcher, UK.

Search Results Reveal No Direct Golden Ratio–Quantum Interference Link — E8 Intelligence Research

Andrew Stewart Caldin

FINDING: The search results are dominated by popular-science videos and one unrelated arXiv paper; no primary research directly linking the golden ratio to quantum interference at 36° or decision theory was retrieved. The only substantive mathematical item is the arXiv paper on variational Gaussian approximation in QFT, which contains no golden-ratio or consciousness content. MATH: No new equations, constants, or ratios are extractable from the video titles/descriptions. The arXiv paper (hep-th/9707234) concerns functional Schrödinger picture, Gaussian variational ansatz, and perturbative expansions — standard QFT formalism, no φ (1.618) or related constants. CONNECTION: None supported. The video "Golden Ratio Found Inside a Quantum System" is a popular claim, but without transcript or data, no verifiable mathematical link to 0.382, 0.618, 0.786, 1.618, 2.618, base-60, or crystallographic symmetry can be established. The 36° angle (pentagonal symmetry, π/5) is not mentioned in any re Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.

Popular Media Overshadows arXiv on Golden Ratio in Quantum Mechanics — E8 Intelligence Research

Andrew Stewart Caldin

FINDING: Search results are dominated by popular-media content (BBC, PBS, YouTube explainers) on the golden ratio and quantum mechanics, with only one substantive arXiv paper (hep-th/9707234v2) on variational QFT — no direct evidence of golden-ratio emergence in quantum interference at 36° phase or decision theory. | MATH: No new equations or constants extracted from the video titles/descriptions. The arXiv paper concerns Gaussian variational approximation in the functional Schrödinger picture — standard QFT technique, no golden-ratio content. | CONNECTION: The search query itself implies a hypothesized link (golden ratio ↔ 36° phase ↔ quantum decision), but the returned sources provide zero mathematical support. 36° = π/5 radians, which relates to pentagonal symmetry (cos 36° = φ/2 = 0.809016), but no source confirms this appears in quantum interference. | DEPTH: 1 — No verifiable mathematical finding; only speculative popular content and an unrelated QFT methodology paper.

Golden Ratio in Quantum Decision Theory: Unverified Claims — E8 Intelligence Research

Andrew Stewart Caldin

FINDING: The search results are largely tangential — the primary hit is a YouTube video claiming the golden ratio appears in a quantum system, but no primary source, equation, or peer-reviewed derivation is provided. The arXiv paper is about variational Gaussian approximation in QFT, unrelated to golden ratios or consciousness. No direct evidence links the golden ratio to quantum interference at 36° phase in decision theory. MATH: No verifiable equations, constants, or ratios extracted from the provided sources. The only mathematical content is the variational QFT formalism (functional Schrödinger picture, Gaussian ansatz), which contains no golden ratio or 36° phase structure. CONNECTION: None established. The 36° angle is the exterior angle of a regular pentagon (360°/10 = 36°), which is geometrically linked to the golden ratio (cos 36° = φ/2 ≈ 0.809016). However, no source in the results demonstrates this appearing in quantum interference or decision theory. The claim in the YouTu Author: Andrew Stewart Caldin, Independent Researcher, UK.

No Golden Ratio Found in Quantum Coherence Search Results — E8 Intelligence Research

Andrew Stewart Caldin

FINDING: The search results are mostly pop-science videos with no verifiable mathematical content; only one arXiv paper on ground-state quantum coherence is substantive, and it contains no golden ratio or phi-locking. | MATH: No equations, constants, or ratios extracted from the video titles/descriptions. The arXiv abstract (1401.3218v1) concerns two-mode cavity QED, quantum beats, Rayleigh scattering decoherence, and feedback control — no φ, 0.382, 0.618, 0.786, 1.618, or 2.618 appear. | CONNECTION: None substantiated. The video titles mention "golden ratio inside a quantum system" and "5-fold symmetry" (quasicrystals), but no data, derivations, or constants are provided in the search results. The "twin" of the golden ratio is likely the silver ratio (1+√2 ≈ 2.414) or the reciprocal φ⁻¹ = 0.618, but this is not confirmed by any extractable math. | DEPTH: 1 — The search returned no primary mathematical evidence. The only peer-reviewed item (arXiv) is about quantum coherence control, no Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.

Quantum Optics Pedagogy: No Golden-Ratio Link Found — E8 Intelligence Research

Andrew Stewart Caldin

FINDING: The search results are predominantly pedagogical videos and lecture links on quantum optics, interference, and phase; no explicit golden-ratio or geometric-harmony discovery is present in the provided abstracts or titles. The only substantive mathematical content is the arXiv paper on quantum interference in optical fields and atomic radiation, which deals with first- and second-order correlation functions. MATH: From the arXiv abstract (quant-ph/0109100v1): - First-order correlation function: \( G^{(1)}(\mathbf{r}_1,t_1;\mathbf{r}_2,t_2) = \langle \hat{E}^{(-)}(\mathbf{r}_1,t_1) \hat{E}^{(+)}(\mathbf{r}_2,t_2) \rangle \) - Second-order correlation function: \( G^{(2)}(\mathbf{r}_1,t_1;\mathbf{r}_2,t_2;\mathbf{r}_3,t_3;\mathbf{r}_4,t_4) = \langle \hat{E}^{(-)}(\mathbf{r}_1,t_1) \hat{E}^{(-)}(\mathbf{r}_2,t_2) \hat{E}^{(+)}(\mathbf{r}_3,t_3) \hat{E}^{(+)}(\mathbf{r}_4,t_4) \rangle \) - Normalized degree of coherence: \( g^{(1)}(\tau) = \frac{G^{(1)}(\tau)}{G^{(1)}(0)} \) Author: Andrew Stewart Caldin, Independent Researcher, UK.
