Disappearance of Schwinger's string at the charge - monopole "molecule"

TL;DR

This paper demonstrates that the total momentum operator of a charge-monopole system is equivalent to that of a symmetric quantum top, showing the string independence of Dirac's quantization and the disappearance of Schwinger's string, with implications for diatomic molecules.

Contribution

It reveals the equivalence of the charge-monopole momentum operator to a quantum top, elucidating string independence and properties akin to diatomic molecules.

Findings

Schwinger's string disappears in the charge-monopole system

Total momentum operator is equivalent to that of a symmetric quantum top

Properties similar to diatomic molecules are observed

Abstract

An equivalence of total momentum operator of charge - monopole system to the momentum operator of a symmetrical quantum top is observed. This explicitly shows the string independence of Dirac's quantization condition leading to disappearance of Schwinger's string and reveals some properties of diatomic molecule for this system.
