We show that the strong CP problem is solved in a large class of compactifications of string theory. The Peccei-Quinn mechanism solves the strong CP problem if the CP-breaking effe…
A Cosmological Constant That is Too Small
Mehmet Demirtas, Manki Kim, Liam McAllister +2
We construct a vacuum of string theory in which the magnitude of the vacuum energy is in Planck units. Regrettably, the sign of the vacuum energy is negative, and som…
Small Cosmological Constants in String Theory
Mehmet Demirtas, Manki Kim, Liam McAllister +2
We construct supersymmetric vacua of type IIB string theory in compactifications on orientifolds of Calabi-Yau threefold hypersurfaces. We first find explicit orie…
Superradiance in String Theory
Viraf M. Mehta, Mehmet Demirtas, Cody Long +3
We perform an extensive analysis of the statistics of axion masses and interactions in compactifications of type IIB string theory, and we show that black hole superradiance exclud…
