Evolution of superconducting string currents

C. J. A. P. Martins, E. P. S. Shellard

Resumo
We extend the velocity-dependent ‘one-scale' model of string evolution to superconducting strings by introducing a simple model for the evolution of the currents. This is based on the dynamics of a ‘superconducting correlation length'. We derive the relevant evolution equations and discuss the importance of plasma effects. Some consequences of our results are also suggested.
