A minimalist approach to conceptualization of time in quantum theory

TL;DR

This paper proposes a minimalist, mathematically grounded approach to conceptualizing time in quantum theory, suggesting that time is not fundamental but emerges locally within quantum systems.

Contribution

It introduces a local time concept that avoids the traditional Newtonian postulate, redefining time as an emergent property in quantum systems.

Findings

Time is not fundamental in quantum theory.

Local time can be attributed to quantum systems without the Newtonian postulate.

Time emerges as an approximate property within quantum subsystems.

Abstract

Ever since Schrodinger, Time in quantum theory is postulated Newtonian for every reference frame. With the help of certain known mathematical results, we show that the concept of the so-called Local Time allows avoiding the postulate. In effect, time appears as neither fundamental nor universal on the quantum-mechanical level while being consistently attributable to every, at least approximately, closed quantum system as well as to every of its (conservative or not) subsystems.
