Flux tube dynamics in the dual superconductor

TL;DR

This paper investigates the dynamic behavior of flux tubes in a dual superconductor, revealing oscillations, collapse, and radiation phenomena through plasma simulations.

Contribution

It introduces a dynamic model of flux tube oscillations and flux radiation in a dual superconductor, extending static analyses to include time-dependent effects.

Findings

Flux tubes exhibit oscillatory behavior due to charge dynamics.

Electric flux is strongly radiated into the superconductor across coupling regimes.

Flux tube collapse and re-expansion are driven by charge acceleration and screening.

Abstract

We have studied plasma oscillations in a flux tube created in a dual superconductor. Starting from a static flux tube configuration, with electric charges at either end, we release a fluid of electric charges in the system that accelerate and screen the electric field. The weakening of the electric field allows the flux tube to collapse, and the inertia of the charges forces it open again. We find strong radiation of electric flux into the superconductor in all regimes of couplings.
