TL;DR

This paper introduces a variant of discrete quantum gravity with a naive continuum limit, showing confinement phenomena in early universe conditions and discussing the noncompact packing of quantized fields in momentum space.

Contribution

It proposes a new discrete quantum gravity model with a naive continuum limit and analyzes confinement and field mode packing in early universe scenarios.

Findings

Confinement of 'color' occurs at early universe stages.

High-temperature expansion is valid in a highly compressed universe.

Noncompact packing of quantized field modes in momentum space is significant.

Abstract

Some variant of discrete quantum theory of gravity having "naive" continuum limit is constructed. It is shown that in a highly compressed state of universe a sort of "high-temperature expansion" is valid and, thus, the confinement of "color" takes place at early stage of universe expansion. In the considered theory any nontrivial representation of the local Lorentz group (i.e. spinor, vector and so on fields) play the role of color. The arguments are given in favor of a significant noncompact packing of quantized field modes in momentum space.
