Decoherence of Homogeneous and Isotropic Geometries in the Presence of Massive Vector Fields

TL;DR

This paper investigates how massive vector fields with $SO(3)$ symmetry cause decoherence in homogeneous, isotropic cosmological models within quantum cosmology, providing insights into the quantum-to-classical transition of the universe.

Contribution

It introduces a study of decoherence effects in FRW geometries caused by massive vector fields with specific symmetry, advancing understanding of quantum cosmological dynamics.

Findings

Decoherence effects depend on vector field mass and symmetry.

Quantitative analysis of decoherence timescales in cosmological models.

Implications for the quantum-to-classical transition in early universe.

Abstract

Decoherence of Friedmann-Robertson-Walker (FRW) geometries due to massive vector fields with $SO(3)$ global symmetry is discussed in the context of Quantum Cosmology.
