Flux tube dynamics in the dual superconductor

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