abstract
We present analytic and numerical results for the evolution of currents on superconducting strings in the classical $U(1) \times U(1)$ model. We derive an energy functional for the currents and charges on these strings, establishing rigorously that minima should exist in this model for loops of finite size (vortons) if both charge and current are present on the worldsheet. We then study the stability of the currents on these strings, and we find an analytic criterion for the onset of instability (in the neutral limit). This limit specifies a lower maximal current than previous heuristic estimates. We conclude with a discussion of the evolution of loops towards their final vorton state in the model under consideration.

Stochastic Gravitational Wave Background from Chiral Superconducting Cosmic Strings
Superconducting cosmic string loops emit vector radiation whose strength is fitted in this paper; including this channel suppresses the predicted gravitational wave background for strong coupling and can make the spec...

Vortons with Abelian and non-Abelian currents and their stability
Vortons exist numerically in U(1)xU(1) and U(1)xSO(3) global models, obey an approximate Regge relation, decay into spinning Q-balls above a critical frequency, and prefer equatorial internal configurations.
