Revisiting the classical electron model in general relativity

TL;DR

This paper extends classical electron models within general relativity by using a quadratic equation of state, resulting in a charged fluid model that closely matches the physical properties of an electron.

Contribution

It introduces a new charged fluid model with a quadratic EoS in general relativity, enhancing the classical electron model with improved physical property alignment.

Findings

Model nearly satisfies electron's physical properties

Uses quadratic EoS for matter source

Extends classical electron model in GR

Abstract

Electron is modeled as a spherically symmetric charged perfect fluid distribution of matter. The existing model is extended assuming a matter source that is characterized by quadratic EoS in the context of general theory of relativity. For the suitable choices of the parameters, our charged fluid models almost satisfy the physical properties of electron.
