Realistic quantum fields with gauge and gravitational interaction emerge in the generic static structure

TL;DR

This paper demonstrates how realistic gauge and gravitational quantum fields naturally emerge from static, discrete structures, with their evolution governed by unchanging laws and the Born rule arising dynamically, addressing foundational issues in quantum physics.

Contribution

It introduces a framework where gauge and gravitational quantum fields emerge from static entities, with evolution governed by invariant laws and the Born rule arising dynamically.

Findings

Emergent quantum fields arise from static distributions.

Quantum evolution is many-world but with finite branches.

The Born rule and macroscopic determinism emerge dynamically.

Abstract

We describe how physical universes that are composed of gauge and gravitationally interacting bosonic and fermionic quantum fields arise from the generic discrete distribution of many quantifiable properties of arbitrary static entities. Alternate presentations of the smooth coarse-graining (fit) for this discrete distribution compose probability-related evolving wave function of the fields' dynamical modes. Their gauge modes, being symmetry transformations, and constrained modes require no additional material structure. We prove that evolution of any origin for which the quantum superposition principle is absolute cannot be governed by specific laws. In contrast, locally supersymmetric quantum fields that emerge as described from the basic discrete distribution evolve by unchanging and closed physical laws. The emergent quantum evolution is many-world; yet its Everett's branches whose norm diminishes below a positive threshold cease to exist. Then some experiments that for the standard Everett view would seem safe are instead fatal for the participants. The Born rule arises dynamically in emergent systems with extended regular past. It and, consequently, quasi-deterministic macroscopic evolution emerge in systems that allow cosmological inflation but not in typical random ones. This resolves the Boltzmann brain problem. We explain how inflation creates new physical degrees of freedom around the Planck scale. Quantum entanglement for the emergent fields is trivial because their wave function, up to its representation, is material.
