Comment on "Possibility of small electron states"

TL;DR

This paper critiques a previous interpretation of the electron wave function as a classical field, arguing it leads to negative energy densities and unphysical velocities exceeding the speed of light.

Contribution

It provides a critical analysis showing the flaws in interpreting the electron wave function as a classical field, challenging prior assumptions.

Findings

Energy-density can be negative, invalidating classical field interpretation

Electron velocity can become infinite, contradicting relativistic constraints

Previous claims about electron speed limitations are incorrect

Abstract

It is shown that the interpretation of the electron wave function as a classical field is untenable because the so called energy-density defined in \cite{seb} takes on negative values in some regions. The claim that the velocity of the electron never exceeds the speed of light is also invalid. The velocity, as defined by the author, becomes even infinite at some points.
