Averaged Methods for Vortex-String Evolution
arXiv:cond-mat/9607093 · doi:10.1103/PhysRevB.56.10892
Abstract
We discuss friction-dominated vortex-string evolution using a new analytic model recently developed by the authors. By treating the average string velocity, as well as the characteristic lengthscale, as dynamical variables, we can provide a quantitative picture of the complete evolution of a vortex-string network. Previously known scaling laws are confirmed, and new quantitative predictions regarding loop production and evolution are made.
