摘要
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. (C) 1998 Elsevier Science B.V. All rights reserved.
