Title Black holes in string theory: entropy and microstates
Author Σακελλαρίου, Ιωάννης
Thesis advisor Νιάρχος, Βασίλειος
Abstract This thesis investigates black hole solutions involving branes, focusing on the entropy of 2-charge and 3-charge systems, the fuzzball proposal, and superstrata constructions. We explore how D-brane configurations account for black hole microstates, matching the Bekenstein-Hawking entropy. The fuzzball proposal is examined as a resolution to the black hole information paradox, suggesting that black holes are composed of horizonless, smooth microstates. Additionally, we present superstrata, which extend the fuzzball framework to provide a richer spectrum of microstate geometries for the 3-charge black hole. Our study aims to enhance the understanding of black hole microstates within the framework of string theory and especially supergravity.
