Coevolution of Quantum Wave Functions and the Friedmann Universe

TL;DR

This paper discusses how quantum wave functions and the Friedmann universe coevolve, explaining phenomena like redshift and energy changes, challenging the assumption of isolated quantum systems in an expanding universe.

Contribution

It revisits Schrödinger's 1939 derivation showing quantum systems coevolve with spacetime, highlighting the incompatibility of isolated quantum assumptions with relativity.

Findings

Quantum wave functions coevolve with spacetime geometry.

Schrödinger's derivation explains Hubble redshift.

Isolated quantum system assumption is incompatible with relativity.

Abstract

Erwin Schrodinger (1939) proved that quantum wave functions coevolve with the curved spacetime of the Friedmann universe. Schrodinger's derivation explains the Hubble redshift of photons in an expanding universe, the energy changes of moving particles, and establishes the coevolution of atoms and other quantum systems with spacetime geometry. The assumption often made that small quantum systems are isolated and that their properties remain constant as the Friedmann universe evolves is incompatible with relativistic quantum mechanics and with general relativity.
