The Electron as a Non-Perturbative Toroidal Soliton

This paper proposes a deterministic, non-perturbative model of the electron as a topologically protected toroidal soliton within the Euler–Heisenberg vacuum. By deriving mass from rotational inertia and spin from phase-closure resonance, the model provides a mechanical foundation for quantum properties. We derive the electron g-factor as a geometric invariant of dual-axis circulation and identify the fine-structure constant as a stability parameter for radiative confinement. Most significantly, we propose an experimental test involving structural diffraction divergence in high-gradient fields (Gold vs. Silicon) to distinguish the toroidal soliton from the standard point-particle model.
