Positronium collapse and the maximum magnetic field in pure QED

TL;DR

This paper investigates the maximum magnetic field in pure QED where positronium binding energy compensates its rest mass, potentially revealing insights into vacuum structure and the falling to the center phenomenon.

Contribution

It introduces a maximum magnetic field in QED where positronium energy levels fully compensate its rest mass, linking magnetic field limits to vacuum structure.

Findings

Identifies a maximum magnetic field where positronium binding energy equals its rest mass.

Shows the disappearance of the energy gap between electron-positron system and vacuum at this field.

Suggests a connection between the maximum magnetic field and vacuum structure.

Abstract

A maximum value for the magnetic field is determined, which provides the full compensation of the positronium rest mass by the binding energy in the maximum symmetry state and disappearance of the energy gap separating the electron-positron system from the vacuum. The compensation becomes possible owing to the falling to the center phenomenon. The maximum magnetic field may be related to the vacuum and describe its structure.
