Convergence Encyclopedia: C04 — Symmetry-Breaking / Bifurcation
F1 — Tier. T1 (established across multiple fields, no unified theory but well-documented phenomenology).
F2 — Sources.

F3 — Domains. Cosmology (electroweak symmetry-breaking), condensed matter (superconductivity, ferromagnetism), biology (morphogenesis, left-right asymmetry), particle physics (Higgs mechanism).
F4 — Scale. Subatomic (Higgs field, ~10⁻²⁸ m) → organismal development (morphogenesis, ~10⁻³ m) → cosmic structure formation (~10²⁶ m).
F5 — Falsifier. A complex structure with no prior symmetric state — a system that displays broken symmetry without any identifiable more-symmetric precursor configuration. This would imply spontaneous structure formation without symmetry-breaking, undermining the paradigm.
F6 — Rival (strongest form). Structure arises from local interactions without any global symmetry-breaking phase transition. Many patterns (e.g., some cellular automata, diffusion-limited aggregation) produce complex structure through purely local rules; the “symmetry-breaking” description is a post-hoc overlay, not a causal mechanism. The appearance of a symmetric prior is a modeling convenience, not a physical history. (Anderson 1972 Science 177:393; Goldenfeld & Woese 2011 Science 332:1373.)
F7 — Independence. HIGH. Landau (condensed matter phase transitions, USSR), Anderson (many-body physics, gauge invariance, Bell Labs), Higgs (particle physics, Edinburgh), Turing (mathematical biology, Manchester) — four fields, three countries, zero institutional or intellectual borrowing. Each discovered symmetry-breaking independently in their domain.
F8 — Pattern type. Structural.
F9 — Maps. A1 (foundational structure), A7 (pattern geometry).
