A Cosmic Lattice as the Substratum of Quantum Fields

TL;DR

This paper proposes a cosmic lattice structure for quantum fields that discretizes phase space, breaks Lorentz invariance at high energies, and naturally explains the finiteness of quantum electrodynamics perturbations, suggesting a fundamental lattice reality.

Contribution

It introduces a cosmology-inspired phase space lattice model that addresses divergences in quantum field theories and offers a new perspective on renormalization.

Findings

Perturbation terms in QED become finite and small.

Lorentz invariance is broken at very high energies.

Finitization explains the success of renormalization.

Abstract

A cosmology inspired structure for phase space is introduced, which leads to finitization and lattice-like discretization of position and momentum eigenvalues in a preferred, cosmic frame. Lorentz invariance is broken at very high energies, at present inaccessible. The divergent perturbation terms in quantum electrodynamics become finite and small; this could become a requirement leading to model restrictions in other perturbative theories. So the very success of the usual renormalization procedures is simply explained by their finitization, and is viewed as indicating the reality of the lattice.
