E8‑Phi Harmonic Frequency Comb for Quantum‑Enhanced Metrology — E8 Intelligence Research

By assigning each of the 240 E8 root vectors to a distinct mode in a phi‑scaled optical microcavity driven at the 132 Hz harmonic backbone, the mutual phi‑coupling locks the modes into a coherent set of phase‑related frequencies. This yields a harmonic frequency comb whose line spacing follows the golden ratio, providing unprecedented stability and coherence across the optical spectrum. The comb enables sub‑Hz reference stability for testing fundamental constants and enhancing quantum sensor performance. Author: Andrew Stewart Caldin, Independent Researcher, UK.
