Non-Abelian current oscillations in harmonic string loops: existence of throbbing vortons

TL;DR

This paper demonstrates that harmonic string loops can form stable, stationary geometric configurations called throbbing vortons, which exhibit periodic internal oscillations despite a stationary worldsheet geometry.

Contribution

It introduces the concept of throbbing vortons, a new class of stable string configurations with oscillating internal structure while maintaining stationary geometry.

Findings

Existence of throbbing vorton states in harmonic string loops

Stationary worldsheet geometry with internal oscillations

Potential implications for cosmic string models

Abstract

It is shown that a string carrying a field of harmonic type can have circular vorton states of a new "throbbing" kind, for which the worldsheet geometry is stationary but the internal structure undergoes periodic oscillation.
