Beyond Landau: Symmetry Breaking and Wigner-Eckart Corrections in Infinite Systems — E8 Intelligence Research
Year: 2026
Type: preprint
Abstract: FINDING: Phase transitions may occur without spontaneous symmetry breaking, challenging the Landau paradigm; corrections to Wigner-Eckart relations emerge from broken symmetry in infinite systems. | MATH: Landau paradigm: order parameter φ → 0 above T_c, φ ≠ 0 below; spontaneous breaking of group G → subgroup H; Wigner-Eckart: ⟨j'm'|T^k_q|jm⟩ = ⟨jm;kq|j'm'⟩ · (reduced matrix element); correction term ∝ (1/N) Σ_i ⟨[Q_a, T^k_q]⟩ for broken generators Q_a, with N → ∞. | CONNECTION: Broken symmetry groups map to root systems (e.g., SU(2)→U(1) corresponds to A₁ root lattice; crystallographic point groups 2, 3, 4, 6-fold rotations — ratios 1/2, 1/3, 1/4, 1/6 — mirror base-60 fractions 0.5, 0.333, 0.25, 0.1667; no direct 0.618/1.618 ratio appears in these findings). | DEPTH: 7 — The Wigner-Eckart correction is a precise mathematical result (arXiv:2007.03539), but the "twin phases" and general claims remain qualitative; the challenge to Landau's universality is profound but not yet crystallize Author: Andrew Stewart Caldin, Independent Researcher, UK.
