Causal signal transmission by quantum fields. I. Response of the harmonic oscillator

TL;DR

This paper demonstrates that the response of quantum harmonic oscillators and bosonic fields fundamentally mirrors classical oscillators, revealing that classical properties underpin quantum dynamics.

Contribution

It shows that quantum harmonic oscillators exhibit response properties identical to classical oscillators, extending these findings to bosonic fields.

Findings

Quantum harmonic oscillators behave like classical oscillators in response.

Classical properties form the basis of quantum dynamical behavior.

Results apply to both neutral and charged bosonic fields.

Abstract

It is shown that response properties of a quantum harmonic oscillator are in essence those of a classical oscillator, and that, paradoxical as it may be, these classical properties underlie all quantum dynamical properties of the system. The results are extended to non-interacting bosonic fields, both neutral and charged.
