EPR measurement and the origin of cosmic density fluctuations

TL;DR

This paper models the origin of cosmic density fluctuations as a spontaneous symmetry breaking process within quantum mechanics, linking measurement dynamics to early Universe structure formation.

Contribution

It introduces a novel application of the generalized effective action method to describe quantum measurement and cosmic density fluctuation generation as symmetry breaking.

Findings

Violation of Bell inequality demonstrated in the model

Density fluctuations arise from spontaneous symmetry breaking

Provides a unified quantum-mechanical framework for cosmology

Abstract

We explore consistent application of quantum mechanics to the objects in the Universe and in laboratories. The measurement dynamics in quantum mechanics is modeled as a physical process of spontaneous symmetry breaking (SSB) which is described by the generalized effective action method. A violation of the Bell inequality is observed in this model and the generation of the density fluctuations in the early Universe is described as the SSB process of the spatially translational symmetry.
