Journal ArticleDOI
Vacua with Small Flux Superpotential
TL;DR: This work describes a method for finding flux vacua of type IIB string theory in which the Gukov-Vafa-Witten superpotential is exponentially small, at large complex structure and weak string coupling.
Journal ArticleDOI
The Kreuzer-Skarke axiverse
TL;DR: In this paper, the authors studied the topological properties of Calabi-Yau threefold hypersurfaces at large h 1,1 and showed that the Kahler cone of X is very narrow at large H 1, 1, and as a consequence, control of α′ expansion in string compactifications on X is correlated with the presence of ultralight axions.
Journal ArticleDOI
Superradiance in String Theory
TL;DR: In this article, an extensive analysis of the statistics of axion masses and interactions in compactifications of type IIB string theory is performed, and it is shown that black hole superradiance excludes some regions of Calabi-Yau moduli space.

The Kreuzer-Skarke Axiverse
TL;DR: In this article, the authors studied the topological properties of Calabi-Yau threefold hypersurfaces at large (h 1,1) and showed that the Kahler cone is very narrow at large, and as a consequence, control of the expansion in string compactifications on these cycles is correlated with the presence of ultralight axions.
Journal ArticleDOI
Conifold Vacua with Small Flux Superpotential
TL;DR: In this article, a method for finding flux vacua of type IIB string theory in which the flux superpotential is exponentially small and at the same time one or more complex structure moduli are stabilized near to conifold points is introduced.
