Quantum Mechanical Observers and Time Reparametrization Symmetry

TL;DR

This paper explores how quantum measurement processes relate to the spontaneous breaking of time reparametrization symmetry, proposing that measurement degrees of freedom are linked to Goldstone modes of this symmetry.

Contribution

It introduces a novel framework connecting quantum measurement to Goldstone modes arising from broken time reparametrization symmetry.

Findings

Measurement degrees of freedom originate from Goldstone modes.

Quantum states are classified by their non-unitary temporal behavior.

The framework links quantum observation to symmetry breaking phenomena.

Abstract

We propose that the degree of freedom of measurement by quantum mechanical observers originates in the Goldstone mode of the spontaneously broken time reparametrization symmetry. Based on the classification of quantum states by their non-unitary temporal behavior as seen in the measurement processes, we describe the concepts of the quantum mechanical observers via the time reparametrization symmetry.
