Candidate de Sitter Vacua / McAllister, Liam (Cornell U., Phys. Dept.) ; Moritz, Jakob (CERN) ; Nally, Richard (Cornell U., Phys. Dept.) ; Schachner, Andreas (Cornell U., Phys. Dept. ; Munich U., ASC)
We construct compactifications of type IIB string theory that yield, at leading order in the $\alpha^\prime$ and $g_s$ expansions, de Sitter vacua of the form envisioned by Kachru, Kallosh, Linde, and Trivedi. [...]

de Sitter vacua at leading order? / Moritz, Jakob Ulrich (speaker) (CERN)
In this talk I will present the first explicit example of a de Sitter vacuum as envisioned by Kachru, Kallosh, Linde and Trivedi 20 years ago, in the tree level approximation in both the string loop and $\alpha’$ expansion. I will begin by summarizing the construction of all the relevant components, from Calabi-Yau orientifolds, and a mechanism to generate exponentially small superpotentials from quantized fluxes, to the explicit stabilization of hundreds of Kähler moduli via non-perturbative D3-instantons on cycles that satisfy Witten’s rigidity conditions, and the construction of warped Randall-Sundrum throats that can host SUSY breaking uplifts.

Computational Mirror Symmetry / Demirtas, Mehmet (IAIFI, Cambridge ; Northeastern U.) ; Kim, Manki (MIT, LNS) ; McAllister, Liam (Cornell U.) ; Moritz, Jakob (Cornell U. ; CERN) ; Rios-Tascon, Andres (Cornell U.)
We present an efficient algorithm for computing the prepotential in compactifications of type II string theory on mirror pairs of Calabi-Yau threefolds in toric varieties. Applying this method, we exhibit the first systematic computation of genus-zero Gopakumar-Vafa invariants in compact threefolds with many moduli, including examples with up to 491 vector multiplets..

Moduli space reconstruction and Weak Gravity / Gendler, Naomi (Cornell U.) ; Heidenreich, Ben (Massachusetts U., Amherst) ; McAllister, Liam (Cornell U.) ; Moritz, Jakob (Cornell U. ; CERN) ; Rudelius, Tom (UC, Berkeley)
We present a method to construct the extended Kähler cone of any Calabi-Yau threefold by using Gopakumar-Vafa invariants to identify all geometric phases that are related by flops or Weyl reflections. In this way we obtain the Kähler moduli spaces of all favorable Calabi-Yau threefold hypersurfaces with $h^{1,1} \le 4$, including toric and non-toric phases. [...]

Gaugino condensation and small uplifts in KKLT / Moritz, Jakob (speaker) (Deutsches Elektronen-Synchrotron DESY)
We argue that ten-dimensional consistency requirements in the form of a certain tadpole cancellation condition can be satisfied by KKLT type vacua of type IIB string theory. The stress caused by the restoring force that the stabilization mechanism exerts on the volume modulus once supersymmetry gets broken can be seen to ensure this dynamically. [...]
