Charge-velocity-dependent one-scale model for cosmic string network evolution |
|
Résumé |
The Velocity One Scale (VOS) model for cosmic string network evolution is
extended to include possible currents flowing along the strings, and
different regimes are shown to be present in the very simplified case of a
linear equation of state. I’ll present and explain these regimes and discuss
why one can conclude that in the matter-dominated era, the average current
should vanish unless nonlinear effects come to dominate. |
