Title: Tests and exploitations of String Theory: From Dark Energy to Gravitational Waves

Abstract: Although string theory is famously hard to connect with observations, a lot of work is currently done with the aim of both testing it and exploiting its features to address observational puzzles. For instance, the nature of Dark Energy is one of the current big questions in cosmology--within string theory it is intimately tied to the search for de Sitter vacua within its vast landscape of solutions. As an example of exploitation, I will outline a concrete and previously unexplored setup using Casimir energies on extra dimensions that are Riemann flat compact manifolds, where one can look for such de Sitter solutions. I will then turn to Gravitational Waves as probes of extra dimensions and discuss how common ingredients in string compactifications might be key to their observability. We will look at a simple example of a binary system source in the context of a warped braneworld scenario, where we can compare the signals sourced by localised and extended sources, and how these relate to fifth force constraints.
