String theory origin of the primordial universe and its visualisation
Lead Research Organisation:
Swansea University
Department Name: College of Science
Abstract
The project involves development of theoretically consistent models of string theory inflation and their primordial signatures due to the presence of spectator and dynamical fields, such as scalars and vectors, beyond the inflaton field, which generically appear in models of string theory inflation.
Potential signatures are the generation and enhancement primordial gravitational waves, which can thus be detected in future interferometers such as LIGO and LISA, primordial black holes, which can be a dark matter candidate.
A crucial element of the project is the development of numerical techniques to analyse these models, which are not possible to analyse analytically due to their complexity. It also involves the use of machine learning techniques to optimise this analysis and the visualisation of the results, to enhance the understanding of the cosmological signatures.

| Geographic Reach | Local |
| Primary Audience | Schools |
| Results and Impact | Almost 100 pupils came at Swansea University for the "Physics School Christmas Lectures", an annual event that takes place at Swansea University. For such event I gave a talk, 15 minutes long, about the Dark Settor of the Universe (in particular Dark Matter). The students seemed really enjoying the discussion that come after, and they asked questions. The school gave a really good feedback at the end of the session. |

| Description | Dark Matter Day |
| Form Of Engagement Activity | Participation in an activity, workshop or similar |
| Part Of Official Scheme? | No |
| Geographic Reach | Local |
| Primary Audience | Schools |
| Results and Impact | My supervisor organized this event with the aim of reaching young students and show them what people that research Dark Matter study. There were posters, gadgets and public lectures, followed by A&Q sessions. The students were really involved, asking questions, and the school gave a good feedback after the event. |
