Quantum origin of classical properties within the modal interpretations

TL;DR

This paper demonstrates how decoherence and quantum interference lead to classical properties in macroscopic systems through modal interpretations, showing the quantum-to-classical transition.

Contribution

It provides a specific example illustrating the emergence of classical properties from quantum mechanics using modal interpretations.

Findings

Decoherence causes the formation of narrow eigenstates in macroscopic systems.

Quantum interference contributes to the emergence of classical states.

Modal interpretations offer a framework for understanding quantum-classical transition.

Abstract

An example is presented when decoherence and quantum interference gives rise to narrow eigenstates (in coordinate representation) for the reduced density matrix of macroscopic quantum systems. On the basis of modal interpretations this means the emergence of classical properties.
