I report on recent numerical simulations of the simplest field theory with cosmic string solutions, the Abelian Higgs model. We find that random networks of string quickly converge to a scaling solution in which the network scale length $\xi$ increases linearly with time. There are very few loops with sizes less than $\xi$, and the strings are smooth, showing no signs of ``small scale structure''. We claim that particle production is the dominant energy-loss mechanism, not gravitational…

The Rise and Fall of the Cosmic String Theory for Cosmological Perturbations
The cosmic string theory for cosmological fluctuations is a good example of healthy scientific progress in cosmology. It is a well defined physically motivated model that has been tested by
Cosmic strings in axionic-dilatonic gravity
We first consider local cosmic strings in dilaton-axion gravity and show that they are singular solutions. Then we take a supermassive Higgs limit and present expressions for the fields at far


Formation and Evolution of Cosmic Strings
First of all, cosmic strings are not superstrings. Superstring theory is an attempt to supplant field theory as the most fundamental language with which to describe physics. Standard field theories
