A landscape of orientifold vacua
Federico Carta, Jakob Moritz, Alexander Westphal
We present a vast landscape of O3/O7 orientifolds that descends from the famous set of complete intersection Calabi-Yau threefolds (CICY). We give distributions of topological data…
Vacua with Small Flux Superpotential
Mehmet Demirtas, Manki Kim, Liam McAllister +1
We describe a method for finding flux vacua of type IIB string theory in which the Gukov-Vafa-Witten superpotential is exponentially small. We present an example with $W_0 \approx…
Gaugino condensation and small uplifts in KKLT
Federico Carta, Jakob Moritz, Alexander Westphal
In the first part of this note we argue that ten dimensional consistency requirements in the form of a certain tadpole cancellation condition can be satisfied by KKLT type vacua of…
Thraxions: Ultralight Throat Axions
Arthur Hebecker, Sascha Leonhardt, Jakob Moritz +1
We argue that a new type of extremely light axion is generically present in the type IIB part of the string theory landscape. Its mass is suppressed by the third power of the warp…
On uplifts by warped anti-D3-branes
Jakob Moritz, Ander Retolaza, Alexander Westphal
In this note we outline the arguments against the ten-dimensional consistency of the simplest types of KKLT de Sitter vacua, as given in arXiv:1707.08678. We comment on parametriza…
Racing through the swampland: de Sitter uplift vs weak gravity
Jakob Moritz, Thomas Van Riet
We observe that racetrack models for moduli stabilization are in tension with strong forms of the Weak Gravity Conjecture (WGC). Moreover, recently, it was noted that controlled KK…
