On the notion of the photon

TL;DR

This paper proposes a novel interpretation of the photon as an elementary excitation in a fine-grained space, aligning with recent submicroscopic quantum mechanics theories.

Contribution

It introduces a new perspective on the photon, comparing it to phonons, and links it to a space structure and quantum mechanics developed by the author.

Findings

Photon can be considered as an elementary excitation in a fine-grained space

The interpretation aligns with the author's recent submicroscopic quantum mechanics

Supports a new conceptual framework for understanding electromagnetic quanta

Abstract

It is shown that the photon, the quantum of electromagnetic field, allows the consideration in the framework of the scheme which in some aspects is typical for the phonon, an excitation of the crystal lattice of a solid. The conclusion is drawn that the photon may be interpreted as an elementary excitation in a fine-grained space. The corollary is in excellent agreement with the space structure and submicroscopic quantum mechanics, which have recently been constructed by the author in a series of works.
