Emergent Quantum Field Theory from the Universal psi Lagrangian

We show that the full structure of relativistic quantum field theory emerges directly from the UniversalΨ Lagrangian through the functional expansion around a stationary coherent configurationΨ0. The relativistic dispersion relation, Klein–Gordon and Dirac operators, Maxwell and Yang–Mills sectors, canonical commutation relations, propagators, and the multi-particle Fock structureall arise as coherent eigenmodes of the quadratic variational operator. No quantization rules, nogauge principles, and no relativistic postulates are assumed. The resulting quantum field theoryis derived as the unique closed and parameter-free low-energy limit of the universal variationalframework.
