Topological Solitons Seminar: Cosmic vortons

Presented by Paul Sutcliffe, Durham University

11 November 2009 14:15 in CM219

Cosmic vortons are loops of superconducting cosmic string. Vorton solutions will be presented and their stability discussed. The results motivate the study of vorton stability in a lower dimensional system, where analytic results can be obtained within an elastic string description. This involves the calculation of the action density on the string worldsheet and allows explicit formulae to be obtained for quantities such as the transverse and longitudinal propagation speeds. This approach reveals a complicated pattern of intervals of instability.
