Polarization of light and the spin state of photon

TL;DR

This paper compares light polarization and photon spin, arguing that polarization is a clearer concept for explaining light-atom interactions and questioning the fundamental existence of photon spin.

Contribution

It demonstrates that polarization is a more practical and understandable concept than photon spin for describing light interactions and raises questions about the fundamental nature of photon spin.

Findings

Polarization provides a clearer explanation of light-atom interactions.

Photon spin may lack fundamental essence.

Polarization is easier to use than spin for explaining light effects.

Abstract

The comparison of the polarization and spin of light is presented in the paper. It is shown that it is more easier and clearer to use the polarization of the light to explain the effect of the interaction of light and atoms than that of spin of the light. The paper also gives rise to the question whether or not the concept of spin for photon have any essence for its existence.
