Title : Superconducting Cosmic Superstrings
Abstract:
| Recent models of inflation based on string theory predict the formation of a 4-dimensional network of superstrings on a cosmological scale. In this talk, I will show how the degrees of freedom living on these fundamental strings backreact on their spacetime motion in the same way as a neutral persistent current would, rendering these strings effectively superconducting and allowing the possibility of stable string loops. I will then discuss the consequences that these stable loops have for cosmology and as long lived states within perturbative string theory. |
