Top-down models for cosmology, black holes, and holography

Experimental and theoretical results of the past decades suggest that quantum gravity can influence large-scale phenomena in a non-trivial and puzzling way. Dark energy which contributes roughly 68% of the energy of the universe has eluded our understanding for this very reason since its discovery in 1998. In the same spirit, Hawking radiation which emanates from black holes has also left physicists perplexed over the past decades due to its contradictory nature. Bottom-up approaches have failed to explain these phenomena although many attempts have been made. All evidence suggests that a proper understanding requires particle theory that includes also quantum gravity. String theory is one of the few candidates for a consistent quantum theory of gravity. In addition to being a theory which can be applied directly to approach these questions, it also provides its own connection between gravity and quantum theory through the holographic principle.

My project aims to explore this connection between large and small scale physics by building top-down models in string theory. These models will serve to explore strongly coupled field theories through the use of the holographic principle. I will also explore models for microstate geometries of black holes and early universe cosmology.
