Abstract
Topological defects are possible by-products of phase transitions in the early Universe, predicted to have formed via the Kibble mechanism [Kibble, 1976]. An example of a defect are the filament-like cosmic strings, which are an expected and generic prediction of several Beyond the Standard Model theories. As such, detection of cosmic string networks is a primary target for current and next-gen observational probes. However, the need for more accurate forecasts and the description of exotic types of strings often requires more compute power and the means to exploit it.
Superstrings [Tye & Sarangi, 2002] stretched to horizon-scales can be studied using analytical and computational tools from the study of cosmic string networks. In this talk we will focus on using field theory simulations of interconnected strings [Saffin, 2005] to the study the properties of cosmic superstring networks. To do so we made use of our recently developed multi-GPU string simulation [Correia & Martins, 2021].
