Cosmic strings - relativistic vortices in the early universe

Date: 
Tuesday 4th December 2012 - 09:50 to 10:30
Venue: 
INI Seminar Room 1
Session Title: 
Topological evolution in gauge theories and cosmology
Session Chair: 
Tanmay Vachaspati
Abstract: 
In many models of the very early universe, a tangle of relativistic vortices - cosmic strings - are spontaneously formed at a phase transition. I will briefly review the models and observational constraints, compare and contrast cosmic strings with superconductor flux tubes and superfluid vortices, and describe the latest large-scale simulations of their formation and decay.
