Finally, our paper has just been published on JHEP! https://lnkd.in/gXy2gD5Y Together with my amazing collaborators Lukas Kaufmann and Timo Weigand, there we investigate key aspects of five-dimensional theories. In particular, we observe that certain extended two-dimensional objects — known as 'supergravity strings' — can be employed as tools to probe the geometry underlying these theories. By using such strings, one could address key questions about the theory, such as: What is the origin of the five-dimensional theory? What might the extra spatial dimensions look like? And under what conditions could the theory break down, and through which mechanisms? Although, there, our focus is on five-dimensional models (with one spatial dimension more that our Universe!), the methods and insights developed may ultimately shed light on theories more closely connected to observable physics.
