Ordering Dynamics of Topological Defect Networks

Abstract

I report on some work in progress on the dynamics of extended objects in field theories after a rapid phase transition, as is relevant in the early Universe. An analytic technique, originally introduced to approximate the dynamics of topological defects in condensed matter systems, is extended to cover relativistic objects. An exact formula for the area density of domain walls in $D$ dimensions is derived.
