Decoherence, Entanglement and Cosmic Evolution

TL;DR

This paper explores how quantum decoherence and entanglement between different cosmic eras can influence cosmological models, providing observational constraints and insights into the universe's evolution.

Contribution

It introduces a framework for understanding the impact of quantum decoherence and entanglement on cosmic evolution and observational cosmology.

Findings

Entanglement may link different eras of cosmic evolution.

Decoherence imposes dynamical constraints on cosmological models.

Quantum effects could leave observable imprints on the universe's history.

Abstract

The possible imprint of quantum decoherence, in the framework of cosmology, is here investigated. Particular attention is paid to the observational fact that entanglement could lead to the interaction of different eras of cosmic evolution. The role played by decoherence provides the existence of "quantum entanglement" between cosmological eras giving, as observational results, dynamical constraints on the corresponding cosmological models.
