Notes on the second quantization in quantum electrodynamics

TL;DR

This paper critically examines the foundations of second quantization in quantum electrodynamics, highlighting logical inconsistencies despite its successful predictive power and discussing its underlying physical meaning.

Contribution

It questions the logical basis of second quantization in quantum electrodynamics and explores its physical interpretation.

Findings

Second quantization is introduced without sufficient logical justification.

Despite foundational issues, it produces highly accurate experimental predictions.

The physical essence of second quantization is analyzed and discussed.

Abstract

It is demonstrated that the second quantization which is the basis of quantum electrodynamics is introduced without sufficient grounds and even logically inconsistently although it yields extremely accurate predictions that are in excellent agreement with experiment. The physical essence hidden behind the second quantization is discussed as well.
